So forgive me if this is actually a thing, but I personally have not heard anybody talk about it and it’s something I kind of thought of and maybe someone else has already but here it goes. So we all know about pH your water before a feeding and after you’ve added your nutrients well while studying the pH nutrient chart, I thought of something early to late veg. The plants need a higher rate of nitrogen and late flower, they need higher potassium so my way of thinking is that at the beginning of the plants life start off with a low pH around 6.2-6.5 for maximum nitrogen absorption, and towards the end of flower, have the pH closer to 7 for maximum phosphorus and potassium absorption.
