its the fox farm!! this happened to me too but fortunately i did not spray that much on all of them. the one plant that got messed up was the one that had the most spray. the leaves became crispy, yellow,and had brown death spots on them. i trimmed the most damaged leaves off, and everything is fine now. next time you use that stuff, use it extremely sparingly and put it on them before bed time so light dont make it worst, and keep the fan on high to help dry the plants quick.
