Yeah try to dilute it a bit. If something were burning my plants each time at full strength I would cut back the dosage. This is just a suggestion but, what if you did a couple smaller applications instead of one heavy application. I'm guessing you're going to be going the foliar route. I'm thinkng if you sprayed lightly a couple times you wouldn't "shock" the plant so badly. I don't know how the residue build up is and if smaller doses would make this worse though. Hope you get the help you're looking for and good luck with your grow.
