I have another thread going for what I thought was a P defiency but now I don't know what the issue is? Plants have been in the UC for 14 days now. Approx 24in. Tall. My room is dialed with 75-80f 12,000 watts double ended 18 bucket UC system. Chiller keeps water 65-68f no co2 currently being used. Ph swings from 6.3 6.4 down to 5.5 in last 3 days after last water change. Roots all white & health . Running CS veg a&b with .5ml per gal. Cal/Mag I'm on well water. Ppm out the tap is 100 on 700 scale. Ppm in UC is 170 ppm ant top off rez. At 220ppm. Plants drinking 4 gal. In 24 hrs. And eating 10PPM. Went from 160-150 ppm over night. But plants are droopy and look hungery.
