Help! Curling leaves!

[Junnk]

One of my plant' leaves started to curl, not up or down, just curl like a taco. I don't know what it could be. Temps are 77-78 during the day and 65-67 at night. The HPS light is about 12 inches form the top.

Hmmm, what do the roots look like?

Well if it happened suddenly, over 1 day I would blame your light being too close.

i agree light to close its from heat stress. even though your room temps are in check the lumen heat is killing them im almost certain.

It didn't occur over 1 day, more like 5-6 days. New growth comes out normal then curls, light too close? My hand doesn't even get warm when I put my hand by the plant

Did adding a fan help with the problem Pen?

i had the same issues.. but it just went away, from when i asked people said it was from overwatering... i didnt understand that cause im growing in water, but i let the res completely dry out for like half a day and then filled it up and i guess they were right lol, my leaves arent curled up anymore

This can happen from having nute strength too high, try flushing and adding lower ppm
