Why do my leaves look like this?

Why do my leaves look like this?

Possibly over watering?

is that light stress?

sharp decrease in nutes?

probably low light from being underneath. Is it still in veg?

Drooping leaves and curled leaves hmm..... You may be over watering. Let your soil get bone dry when you stick your finger in. Lift the plant up is it heavy? or is it very very light? if it's heavy it's got water and needs to go longer. Make sure temps aren't too high also. 80-81F max 76F is great. Humidity 40-50% PH 6.5 all the basic stuff.

Repot it and check the roots at the same time.

If the root zone smells like rotten lettuce you have a problem.

too much water not enough light
