Yellow and bent leaves

Light stress. Now light 40 cm and leaves is better. Thank you very much.

do you check the pH of the solution and adjust it every time you inafi? if you don't, it starts from there

Looks like light/heat stress to me. Raise your light and see if the canoeing goes away

Hi Martin. We or I need more info to answer your question. If you had a diary so we can see what your feeding or not feeding or how close the light is or if you overwatered or not watered enough. We can't tell from 1 picture and a few words. Yes I can see they are sick. if you want a good answer you need to provide more info. I could guess but that wouldn't be fair to you . Yellow usually means not enough nitrogen. Canoeing of the leaves usually means some sort of light stress or the lights are too close. But if it was heat stress the lower leaves would look normal and they don't? Need more info dude. Chuck.

Looks like heat stress maybe the Lights to low and not enough airflow
