I have an atf in week 3 of flower. about a week ago I noticed the leafs curling up and figured it was heat stress, (which was weird because I have other plants and the same height and have had no problems) so I moved it away from the light a little. that night I fed just phed water. a few days later the leaf tip curl got worse and the tips began to crisp. now the leafs are starting to discolor and die off. not sure whats up.
