I keep my hydro ph from 5.5-6.0 Try my best to keep it right at 5.8 as best I can. During flowering I've noticed my ph flucuates a lot more than it did during veg so I am using larger resevoir to hold more water, to keep the ph less sensitive to change
Lol ok. Well idk what you mean by does it change. Do you change the ph level when watering during flower? I don't realy know. I would think you'd keep it the same ph. I only do hydro
I have seen some "experts" post of raising it as flower progresses to more around 6.7-6.8. Rationale being (a) your lime is gone and that brings it up when using lower ph water (b) the maximum intake for individual nutrients that help flower. With that said, I don't know the truth to it and have never experimented to see.
