5.5-6.8 is the correct ph...dont change it unless your seeing signs of stress on your plants.For harvest....if your "white hairs" are dying faster than there growin,or when 40% of your hairs are brown is a close estimate.
divestoned Reviewed by divestoned 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
