Literally this happened within probably eight hours. This morning they looked fine and I got home from work and they look like this. The last time I used fertilizer was over a week ago and the last watering are used 1 tablespoon of black strap molasses per gallon of water, last night I sprayed them with pyrethrin after dark and kept them shaded in a porch all day today except for two hours of Sun but the product had already dried since I sprayed it yesterday evening. I've been using age old bloom 5-10-5 with Cal mag every 2 to 3 waterings I have been using under the recommended dose and haven't had any problems yet they were beautiful until I just got home from work and they are literally fried what in the hell could have happened???? I'm freaking out here and about to cry!
