i was wondering why i got the burn, i never knew either that i was supposed to wash the spray off? Makes sense I havent had much bug problems lately at all. and the pours are open at dusk and dawn. so the best foliar feeding is at these time? ladybugs awesome as well, check other plants around your peppers i had a bush next to my plants that had shit loads trying to figure out where all these aphid were coming form every day, found a huge populating on the bush neemed it blasted it soaped it now barely any aphids at all.
