It has a a few leaves curling down and they look drier than the rest, something I need to be worried about?
I only used organic nutrients, earthworm humus when preflower started (don't know english name... vermicompost?) each week, watered with banana peals tea every 3 or 4 dys

Hey there so i see the leaves curling/clawing/drooping...and yes this can be sign of a nitrogen toxicity but it can also be many other things overwatering (hows your soil? Is it taking long to dry or is it muddy) , high heats coulled with root stresses (i see your temps are pretty steady in the 90s and 70s at night), i am leaning towards another option because I'm seeing clawing happening all the way back here in week 7...so youve had at least 4 weeks of this, with nitrogen you should start having leaves yellowing and falling off by now similarly to N deficiency theres usually a color and loss of leaves. If you feel like your additives arent blasting it with Nitrogen id definitely explore these other possibilities..the heat the wind the watering and the roots. If you have access to any kelp products theyre extremely useful for helping roots and heat stresses.
I hope you can find the trigger and work it out. Don't give up and keep trying things out. Happy hunting :v:

@ElDuro You are experiencing nitrogen toxicity. No need to panic just feed your plant pure water PHed at 6.3 for about 4 days and Immediately reduce the use of nitrogen in the feeding. The leafs that are effected by Nitrogen toxicity will not visually recover so there is no need to worry if they stay "clawed" or drooping down. The reason your plant is doing this is because as it shifted into flowering it reduced its need for nitrogen severely. I hope this helps you @Elduro be sure to keep us up to date my friend :sunglasses:

Hi @ElDuro! Sorry to say this but you're having a serious nitrogen toxicity (also called "The Claw") that leads to slow bud development and can ruin the final product. Heavily flush your medium with plain pH'd water for a few days and avoid any Nitrogen intakes, no more N, only P+K to help her in bud production. Autos are very sensitive, even to organic nutrients. Hope that will help, keep us up-to-date and happy growing :facepunch:

hi, i exluse lightburn , because your leaves are nicely green, i excluse overwatering because its just the topleaves, I excluse nitrogenexcess. because no burnt tips, and the colour is no to dark. The most possible thing is a windburn, You already can see it in week 8. Maybe the fan to near/ to strong=? happy growing

Hello! Leaves are curling down and clawing : it is a Nitrogen excess. Except for your banana peals tea every other nutrients you used are charged with nitrogen. The leaves will not recover their original shape. You just need to give less N and things will fix naturally. I hope it will help you :grin::+1:

hello ElDuro, basically it's hard to say for sure but this looks like light or wind burn. basically if your light is too close or the fan is blowing directly on the plant it can lead to damage. it's easy to fix just move your fan or your light. If you're quite sure this is not what is happening then it could also be micro-nutrient deficiency from the heavy light schedule, just dilute two soup spoons of molasses and add to the water - it's cheap and it's bio ! hope this helps my friend :rocket:
