pH seems low for most nute uptake. I think he meant the plant on the Right. Airlyn

[Airlyn]

I don’t know what you mean when you said, it’s only bottom?
I really am a newbie. Heck I just started smoking again after 25 years. Growing? 😂
The plant on the left has brown, curling leaves. Perhaps I should have taken better pics. Thank you for any help, I appreciate it.

Hello Airlyn i have the same light as you for one of my tents. Well they could be moved away more from eachother. How is you light hung? What i mean is......is the light hung with short side facing out or long ways width of the tent? I say this because how one maybe getting more light than the other and have you LST or topped them? I do not see light burn nor nute burn perhaps it's the water might boost the cal/mag. I don't use the root stimulator you got roots that are good it looks like why use it?

[Going2fast]

Don't think it's nute burn. Since they are the same strain I would guess a picky pheno. I do soil so can't help with the nutes but since it's only bottom I would suspect a deficiency or ph.

[Airlyn]

first time grower:
Does this look like nute burn or light stress on the right one? I’m guessing nute burn. This one has been behind the other developmentally since the beginning. I probably planted it too deep. I’ve been giving it the same nutes as the other. The seeds were planted the same day Aug 5. Left popped on the 7th. The burnt looking one on the 9th of Aug.They are purple haze autoflower.
In a 3x 3 (I should have just grown one at a time. It looks crowded)
medium is 70% coco, 30% perlite.
my water is very hard. I ph down to 5.8-6.0
i still give cal/mag. Maybe I shouldn’t.
nutrients are coco AB I’m mixing 13ml each to 1 gal of water.
I add in root stimulator, 5ml. Boost was added this week, 6ml to a gal. Lights are viparspectra p2500.
lights off 8 hours a day. They are 18 inches away.

HELP! Brown Spots on Leaves

I just noticed this today. I was planning to "flush" the plant this weekend and harvest 2 weeks from now. Does anyone know what is going on? What if anything should I do? Maybe go ahead and harvest immediately?

[Satyaban]

I think your plants are overfed, FFOF is a hot soil and goes a long way to feed your plants.

[LordShaper]

I appreciate the feedback SoOrbudgal. I was thinking it was a deficiency because the tips weren't burning and the inner leafs were browning. I'll give your suggestion a try. Do you have any tips or links for a good tea and how often to use it?

[SoOrbudgal]

It sounds like to me that your adding alot of ferts or different nutes in combination to the already loaded soil mix. I know it's not " dirt soil " but i call it soil or potting soil. I'd stop the additives raise the light and just use water a couple of times see if it clears up. Remove the large damaged leafs. But i'd quit with all the nutes temporairly then gradually add small amounts of growth tea until you do 12/12. Maybe someone else has different idea but i don't use that much additives in my soil mix.

[LordShaper]

Hi GWE forums help thread heros!

Problem: Two of my plants have leaves that are damaged. I have tried to locate a deficiency that fits the look of it but cannot conclusively say what it is.

Genetics: 9lb. Hammer Feminized by Growers Choice (Bigger plant)+ One unknown bag seed (smaller plant)

Soil: They were planted in Bar Harbor Blend Organic & Natural Potting Soil. When they got big enough I transplanted into 3 gallon fabric pots with Fox Farms Ocean Forest. Each transplant was done with a sprinkle of Great White Mycorrhizae. Planted in 3 gallon fabric pots.

Equipment: 48" x 48" x 80" Vivosun Tent, Spiderfarmer SF4000 18 inches above canopy set at 75%, AC infinity 6inch inline, 2 oscillating fans.

The Nutes: I have the Fox Fam Trio plus I picked up Microbe Brew and Bushdoctor Sledgehammer. Of that I have only used the Big Bloom, Microbe Brew, and 2 feedings of 2mL/Gallon Grow Big. Tips started crisping so I stopped on the Grow Big. I adjust pH of the water with General Hyrdoponics pH+ and pH-. I have Superthrive for emergency use, Fish Shit that I put in every watering, Unsulphured Blackstrap Molasses which I have started adding every other watering at 1 tbsp/Gallon, and GH CaliMagic as my CalMag.

Water: I water when I can pick the whole pot up and it is very light compared to the size of the plants and I cannot feel moisture on the fabric pots. After I add nutrients I pH water to 6.5. I check run-off and its usually 6.4 to 6.7. When I water I add until just before the water will overflow the dirt and cascade down the air-pruned dirt on the inside of the fabric pot. I am looking for run-off that has flowed through the main root mass. When I see it I stop.

What do I think it could be?: Based off of what I can see in the plant diagnoses section of GWE I am leaning towards either a Calcium deficiency or I am overwatering it. This isnt my first grow so I dont believe its over watering.

If you have seen this, please reach out! I am new to this community and would like to learn from you all.

I don't know much but I would lower your lights to no more than 18", also, as they get bigger they will drink up more water so, don't let them run dry. One last thing, I don't know what your plans are but I think 7 plants are too many for a 36X36 tent, My tent is 4X4 I gave one plant away, I should have sold it 7 weeks old but I didn't, to reduce my count to 5 I am moving one around my backyard following the Sun. I could grow 6 but I would have to give up on keeping them a part completely, even with netting. In my 1st time grower's opinion the amount of greenery is more important than the size of the pot. I use 5gal. bags because I want the roots yo have ample room. I think Puglover1 is right about about runoff as well.

[Obsvr]

thanks! They got their first full watering and they responded as well as could be. I'm seeing solid new growth with very healthy leaves. I think by the end of week 3 they'll be ready to top.

[Puglover1]

Maybe shoot for 6.5 pH? Good luck on your grow! Take good care of those ladies. They might be ready to water to the edges to encourage the roots to grow out and down. Damp, not flooded or runoff just consistently damp so you get a feel for the weight.

Hi All

just getting into my first grow and have a small issue I hope you might be able to advise me on. I'm seeing some brown spots on my leaves, but only on a few of the plants. Quick rundown on what i'm working with:

9 auto's in 3 gallon canvas
3x3x6 tent
sun systems 315 LEC
mother earth coco mix
Gen Hydro Fora, Bloom and Grow + calimag

Today is the last day of week 2 and the light has been 24" away from the plants for the last week when I moved them from rapid rooters to their current homes. After reading the tutorials I was worried about over watering and may have under watered them a bit this week. They were given water when the medium felt dry, however I might have gone a bit light in how much I gave them. I've been giving them 1/4 noots + calmag with each watering.

The spots also seem to be where water droplets came to rest after watering. I've been checking and adjusting the PH to 5.5 - 6.5.

Not every plant has it and there isnt a clear pattern inside the tent. The back two rows contain the four plants that seem to be having the issues.

thanks in advance for the help!

***EDIT***

After doing more research it looks like its probably a cal deficiency. I also realized while making this solution that i've completely botched my PH. I had not been stirring after correcting, which means i've been using insanely low PH water (like a strong 4). Tomorrow is their first day where they will get vegetative state watering, so hopefully its onward and upward from here.
