so i want to add a product by Mad Farmer called silica shield to my nutrient solution. It says on the bottle that this product will increase ph. i just purchased a quick ph soil meter. it has two long probes on it. if its correct im looking at about 5.5 to 6.0 on three potted plants. im already in my 3-4 week of flowering. just kinda wanted to add something else to my mix. what do you think?
