some leaves folding down

what causes this?? i was feeding 15-30-30 at half strength for a while before this started showing, last few waters i only used plain water.

Also, most leaves are kinda dark, like a blue green. and some leaves claw down at the tip.

*bump.. anyone know what causes this??

how often do you water

I would have to say either a nute issue OR you are watering too much. Make sure to let the soil get completely dry in the first 1-3 inches before watering again.

water every few days, sometimes every 2, i let the top get pretty dry and the pot light before watering again.

I have the same thing going on and i still havent heard a good explanation.

too much N? i have it in veg but not flower knock back the N go high on the P

how do i knock back the N? the only fert i have is 15-30-15
