I gave it Big Bloom, not Tiger Bloom....1 TSP per gallon of water, got about 1/4 gallon on Monday
Just checked on her, and the leaf in question has very much more pronounced cupping, and the leaf tip is yellow, when a few hours ago it was green?
I'm thinking PH issues, but isnt Promix supposedly PH corrected? Possible nute burn, or maybe a watering issue?
