Ive seen arjian's video and he goes from 5.7-5.5 ph during flowering but I dont want to go that low. Ive been trying to keep it at 6.5 for veg stage but I thought it changed during flowering stage but I guess I misinterpret it but if anyone else has anything else they have been using then I would like to here it.

anyone seen those videos or arjan's ?
