Hey I'm interested in some thoughts... I got some POGK in some 5 gall ebb and flow buckets. PH is 5.7 EC is 1.4 in Coco Peat. Temp 76 RH 45 600 watt aircooled MH 2 feet above. 4 week old. Plants on the left are the ones and the right plant is the healthy one. They got purple stems on the tops...I even have one fan leaf that has purple tip and a bit of speckled purple banding. No growth either...I had the EC much lower and so I bumped it way up to current 1.4 and they haven't done much over the past few days...In person it looks a lot worse basically the leaves are like patchy. Like you'll have some dark green here some light green here some yellow here. For a lot of them there is no particular pattern to this on the leaves... What do you think?
