P.S. whether in veg. or bloom i run my ph at 6.0 (hydro)
Wait right here(book in my lap) it says that primary nutrients cut off below 5.5 pH, It's not optimun but it works.
Chronic Chrissy Reviewed by Chronic Chrissy on . Newbie pH, and flowering questions. About 3 weeks ago buddy popped by with 7 Northern, and 3 Afghani clones, already well rooted, and already zig zaging leaves(I'll bring that up later). Anyways they had to sit in the little rockwool cubes in a 90 degree closet for 2 days while I restocked(it's been a while). It was pretty much a take them or they chuck them situation. Anyways, I got the dryer set up and got them in pots of sunshine mix under a 400 watt MH bulb. We started advanced nutrients, grow, micro, and bloom. Picked up Rating: 5
