I've used vinegar occasionally but am only lowering the pH by .2 Someone correct me if I'm wrong but it's been my understanding the spray water pH doesn't make much difference if you spray right after mixing and don't let the tank sit. The decrease in performance data I've seen was done with a tank mix that sat for three hours.

We have used vinegar, Tri-fol, Li-700 and several other products to reduce ph. I would like to know what products list members prefer to accomplish this task without using a spreader-sticker/penetrant. I've considered using anhydrous citric acid but have found little horticultural data on its use. Thankyou, Mark A. Evans Frankfort, Michigan
