try using CAL MAG and record your amounts each time. red or purple stems/stalks usually mean a cal mag deficiency is there. sometimes its genetics I read..If your plants arent getting enough O2 the leaves will droop and yellow out. which could be root rot like I have experienced. or it could be from overwatering. These were the challenges I faced not too long ago. PH really matters too. i grow in soil and I keep the PH at 6.5. I noticed my PH of the soil would raise really fast. When I did more asking around and research, I found that I was over watering, the ph was out of whack and my ladies had a cal mag issue. I went and fixed one thing at a time and monitored the results. Taking notes is a must. getting an air pump and some air stones helped my plants out immensely. I like to use microbes to keep the roots healthy. But Im still learning and these were my findings as I experienced each issue. Hope this helped. take Care!

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

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.

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.

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

at this point I figure I have nothing to lose!

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]

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.

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.

Good tip given to ya MistaKwick by Rwise

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.

[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

[Rwise]

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

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.

[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.
