i grow in soil and my pH is about 6.4 so far i havent had any problems with that level, altho some may argue its a little low.
dutch.lover Reviewed by dutch.lover on . Confused About Correct PH ok i'm confused over what the PH should ideally be? I read on a thread PH should be 5.5 - 6.5, i've been watering at a PH of 6, and i've just read somewhere cannabis plants like a neutral PH of 7. Can someone please let me know what i should be aiming for as i don't wanna be hurting the plants. Thanks in advance for anyone who can give me some advice ;) Rating: 5
