Nice looking buds, ole buddy, chasing ph around ,would make me catch a bad ass, headache, plus I ain't smart enough to grow DWC, sounds like way to much work, to me, but some people love it.
That's why I'm sticking with living soil, it's almost impossible to screw it up, just water an molasses, and worm compost teas,
They say DWC is faster, idk, but the autos I've been growing lately have been ready ,mostly by day 70 from seed, some might go 80days, but that's still pretty fast.
Your gonna have a nice crop, come harvest time.
