whats this mean?

yoyo! so week 5 of flowering after vegging for 2 weeks. alot of leaves on bottom are curling down and inwards. check out the pics..

the leaves curl under and some leaves twist like corkscrews.

whats this for? i water foxfarm nuts everyother and the past two water have been with epsom salts.

heat stress, over watering, humity? those are my guesses. flush your system and check you ph make sure that is in check too

How often are you watering?
