Yep, Gingerbeard is right. Thrips, or spider mites. Get a loop and look at the bottom of the leaves.

[MistaKwick]

thank you very much,
I sprayed 1 table spoon of neem oil + couple drops of black soap in 1/2 liter of warm water, both on and under the leaves. it was thursday or friday, I watered sunday morning before leaving for a couple of days and will return home on wednesday. I hope the leaves will show some progress, but I will probably give it another spray then just to make sure.

[Gingerbeard]

I'm the one to break it to you. You might be boned. When you get into flowering, there are more things that can go wrong and fewer treatments you have.
There are different opinions in the forum that say you can apply this or that during flowering with no ill effects. Others will say not to put anything on buds. I had to get rid of a crop just a couple weeks before harvest because of WPM because there wasn't anything I could use on flowers.
What to do? Me, personally, my own recourse, what I would never suggest anyone do is start over.

[Rwise]

Never use Neem oil on buds, it has harmed many folks. In veg OK, on the soil OK

[MistaKwick]

Status report: unfortunately, the bugs are still on the leaves and are still very much active
Will spray again and hope for the best
If neem oil fails, whats the next level product that wont harm or "pollute" the flowers (which are still fattening nicely, and which I try not to spray, of course)?
Thanks in advance

ISO as in rubbing alcohol is 100% safe as it evaporates 100%. The alcohol evaporates first leaving water behind, on flowers add a fan for air movement. The mix is 1 part ISO to 8 parts water, I have used it at 50/50 with no problems.
Spinosad should also not be used on buds as it is unknown if it is safe or not, no studies have been done best to err on the safe side.
These are both contact killers which means it needs to get on the pest, and it needs to be done again in no more than 3 days and again in another 3 days, then watch for a return. Spray the under side first, then the top and soak it good, the soil, planter floor wall etc. then give those buds a gentle shake to help get rid of moisture. Oh ya, lights off please, sun is ok, but grow lights are to close and will burn the plant.
Outside the best thing is predator bugs such as lady bugs and praying mantis.
No one like spraying anything on their buds, but sometimes we must.

Good tip given to ya MistaKwick by Rwise

[Ckbrew]

You can use hydrogen peroxide in a spray, but use caution. It needs to be diluted with water to about 1.5% and will burn the plant if the concentration is to high. Start with a test area BEFORE you spray down the entire plant. Wait at least 24 hours to look for burn damage. Add more water if the plants are burned. Peroxide degrades to water and oxygen, so no contaminants to be concerned about. You will be dealing with extra water on the plants which can lead to PWM. Peroxide is a double edge tool, use caution. Also a mask to filter droplets and rinse hands afterward or use gloves.

[MistaKwick]

at this point I figure I have nothing to lose!

Could someone please help me? My babies appear to be drooping and the tops drying out and I can seem to find the problem.



Im a first time grower doing SOG and its a true adventure. Recently I pruned away some fan leafs that were getting in the way of other plants and Im thinking of flipping them to flower as some of them are already too big. The symptoms Im seeing are leafs on the top drying and wilting. I did change their water intake as they are growing quite fast and I suspect I might have given them too much water.

Day: 24
Strain: Critical Kush
Humidity: 45-50%
Lights: Spiderfarmer SE700 (40%)
CO2: 800

I suspect the humidity is low or maybe the lights are too close because I havent been adjusting them to the plants new hight. They seem to be dry on top and the leafs are wilting and slowly dying. This happened recently as I installed CO2 and increased the light to 40% im preparation of flower. Please help my girls.

[SoOrbudgal]

I see that they need fluid way to dry medium and only 24days from sprout that's a pretty quick flip to flower but it's been done won't get as big of harvest doing so with small struggling plants. I'd water more quit removing fans too soon. To dry enviornment in my view.

[men4e]

Thank you for the reply! I will raise the humidity and the lights a bit hopefully the issue will be solved.

Hey, first time grower. So I’m about a little over 8 weeks in. I was told 5 of the girls they were autos but clearly they’re not. So being green I put my mesh pots on concrete. I got them on some pallets now but I’m curious what I should do about the yellow mint leaves. Should I prune the dying leaves and leave the greenish/yellow leaves? I also water them every other day and feed them every other other and keep my ph at 6.5. Each close up picture is a different plant. Only 3 if the 7 girls are starting to turn.

[Puglover1]

I would also remove what's dead and laying atop your soil in the bags. Nice plants, a couple are getting pretty tall. I hope this is your worst hiccup!

[Going2fast]

They look healthy. Just pluck off the completely yellow ones to improve airflow. I leave them till there is no green left. At 8 weeks they are not autos.

HELP!! First time growing got 3 left out of 6. Put last 3 outside one day for about 6hrs and all of them looked fine then my snallest sprout that had just broke soil and made leaves shrank to half its size and the stem has thinned above soil. White dots on back of stem. Drupped peroxide like web told me in diluted form to have chance at killing fungus if thats it and dots have disappeared but leaves are still small and dont look like improving. Got 3 norther lights autos in cups rn under 3 LED lights two smaller on sides and one main light thats 1000w equivelent they put out 700ppfd atleast at hight. I bought scotts top soil fron walmart and mixed it with dirt from backyard cause i was gonna grow outdoors and indoors but since my herd has thinned gonna keep them indoors just bought fabric 3gals and foxfarm cultivation nation to transplant them into in next couple days.. Is this sprout gonna grow? Or should i toss it

[Puglover1]

They look dry, thirsty, maybe try removing some of the chunks from the top of your soil. And add a little something better, something finer but they look very dry in the pics. The green ones I wouldn't mess with other than removing the 'outside' soil and watering them, I wouldn't transplant those yet if it were me, I'd try to better the soil and baby them for a while, let them grow roots and grow more veg, you can slowly top dress with better soil. The others don't look so great. Maybe prop them up with a toothpick. Ya never know. Good luck.

[Hazyn740]

Also i water them a water bottle cap full in morning and at night is that not enough i was afraid of drowning them since theyre so small

[Puglover1]

You should water near the new sprouts in a circle but also do another circle of water about an inch farther outward. You need to get enough water toward the sides and bottoms for the roots to follow the water to grow outward and downward. Some people might use a .5 liter water bottle, I have a very small watering can with a long metal spout that I use for seedlings, it doesn't disrupt the soil. I didn't water daily. If your soil mix isn't totally 'mixed' I'd pull out those chunks of sticks or anything not decomposed, be better to use Miracle Gro organics for the seedlings than that (I know you had other plans, stuff happens). Personally, I'd get these healthy and growing larger before transplanting. Yes, you can remove what you can and add more soil, but don't have foliage touching the soil. As the plant grows taller you will lose a few leaves, makes room for more good soil. Those look like they're growing in a desert, no offense. In pictures here they all look like they need a through soak until a little run off. If you have drainage holes and some air circulation I wouldn't worry about getting them fully watered, just be gentle.

[Hazyn740]

I did that and now look my biggest one just fell over.. I swear this soil had fungus in it its killed everything im an idiot for digging after a rain and having such damp outside soil with root chunks and shit from bushes outback i completely screwed this i guarentee they all die no matter what i do thats just my luck

[Hazyn740]

I litterally WUNG a grow with miracle grow soil at that with its bad rep and with seed i found in my smoke over the years and didnt have nowhere near this many problems

[Puglover1]

If you add a finer soil on top you could help that seedling stand up plus the buried stem should grow roots to help. Too much chunky in there for solo cups.

[Puglover1]

Stake it, tie it, zip ties, whatever if you want it to succeed. That soil still looks dry, the chunky stuff. It's not composted yet.

[Hazyn740]

Above is the plant i found drooping from thirst. Top left is plant that just fell over out of nowhere. Top right plant is one that shriveled up outside one day but didnt die and just never got much better besides dots on stem are gone but hasnt died yet and stays dry shriveled looking no matter how much water its getting



Below is my set up in closet also the smaller lights are off cause my other sprout looked like some one spun it in a circle for hrs leaves hanging down crazy. Gave them all 2 caps of water last night then put sprout domes with vents over them and turn lights off for the night so water would get down in there.. Woke up and my biggest sprout looks like its undergoing damping off? One white spot on stem right at soil line like the other had before i put peroxide on it with a cotton swab and it went away that plant still hasnt shown any improvement other than its alive still barely.. This one i propped with toothpick like you said cause it fell all the way over.. Stem isnt broken yet.. Just got my fox farm soil today but tbh.. These plants already having been contaminated im afraid even if one does survive i dont wanna waste 3 gal of good soil and even all my other money and time i put into this i might just scrap this and try to do my BCN Critical auto, sour diesel auto, and gorilla glue auto seeds right this time im gettin germ cubes and everything so it can just grow in a perfect medium.. Ugh pray for these guys im gonna need all your advice i can to save even one of their lives

[Puglover1]

All I can say is that I'd water them fully, no domes, and I'm not sure of your light's distance. But put some finer soil like M-G or something else on top, after removing some of the chunky outdoor soil. You have sprouted seeds, new plants wanting to grow, you must help them.

[Hazyn740]

I turned big light off and just using two smaller veg lights but it did say they put out 254ppfd at 4" from plant.. I have these at 18" from plant but you said baby them so thats what i thought would help. Big light brings temp up to 83 by itself it gets up to 89 with all of them running. 78 with just these two seedling lights. Now the water doesnt dry up as fast plus i removed as much crap as i could using foxfarm soil to replace and help stand the one sprout that fell over up and also did same to healthy one and watered afterwards and my smaller one really looks happy now the bigger one looks like its starting to grow another section of leaves even tho it fell over and was damping off. The leaves are still droopy in it as you can see in pic its the closest sprout but soil still shows lil water.. Cant water it so just leave it be right? Should i move these lights closer? And as always im grateful for your guys help no matter how its given the soil did look bad i admit.. Thank you so much

[SoOrbudgal]

This is why this site does not recommend using those lights for " sprouts " totally wasted light money. All sprouts need is some CFL 4" above them. Beware when they do begin to grow roots deeper they are going to be reaching upward for more light which will cause those stalks to fall over from the weight of the top of plant. Sorry man

[Hazyn740]

would these work better for sprouts? So then should i turn my big light back on veg setting then and turn those back off or move these sprout lights closer and wait on the bigger light till ive transplanted i just turned all my lights on and moved the sprout lights up outta their range but same height as big light just to supplement it i guess. keeping eye on them just ordered two fans also would it be beneficial to just put them in their 3gal fabric pots so they have better environment or just let them tough it out in these solos with no drainage or air flow for couple more weeks. These are about 2 weeks old

[BU2B]

All in all you’re doing a fine job. Asking for help when needed and learning as you go - like the rest of us. Your plants will be fine with the LED panels just be sure and keep them high enough not to damage the babies. They may stretch a bit but once the stalks firm up they’ll be good to go. You can also use a straw cut about ¼ inch longer than the stem, split it down the middle and place it around your seedlings with the extra length buried in your starting medium. There’s no need to remove the straw as the plants will push it off as the stalks grow. Also for future reference; flat white is at least as effective for light reflection as aluminum foil and easier to maintain. Keep on keeping on and Happy Pharming! 👍🏼

[Puglover1]

Do you have drain holes poked in the bottoms of the solo cups? They look much better! I wouldn't rush the transplant, let them toughen up a little more, the roots should have some room to grow more. I use flat white in my closet, no reflective material. No biggie, the foil is just a PITA when it's not necessary.

[Hazyn740]

Hell yea thank you for the confidence boost the one plant wasnt improving i finally tossed i saw the roots looked like they were dead only reason it was standing up cause i top dressed the soil like you said which i believe made my other healthy Northern Lights really happy. The inside of my closet is flat white paint so i didnt even need the foil!?!? Ive just swapped out dead plant for new BCN Critical XXL and another Gorilla Glue both autos im hoping to fit atleast 3 plants at a time in there and maybe once they start budding have 3 more sprouts growing in the shade of the big girls. Im curious to see if the BCN will catch up to my Northern lights since it seems like its started off slow its like 3 weeks old now and just now starting to grow its next set of leaves. I believe the soil outside my house may be naturally contaminated due to constant soot being released from really big steel plant next to my neighborhood for decades. That makes me wary of trying to grow outdoors in this clear greenhouse tent i bought on amazon. What do you guys think. All my sprouts died mysteriously and by time i learned enough i treated that healthy plants soil with peroxide then water then top dressed like you said and it lools good im just wondering if the dirty soil from outside is making my plant fight harder to live and maybe the all fox farm coco and perlite stuff i got the BCN and GG in will grow it faster since its better shit.. I do have holes poked all around the sides down lower and on the bottoms of the cups so they should be good
