No don’t own corvette.I would never get out of it. Lol. So the nutrients were originally full strength which was my bad for following fox farm schedule and listening to different opinions. But I cut them down to 1/4 of what schedule of what the schedule said, and only added calmag, b12 and silica after I started showing some problems. I believe the reason they said no airgap to start was because of depth of net pots, they said to lower water level after roots were more established (I think, would have to go back and watch video). I’m sure there was some other mistake along the road. I’m not giving up on rdwc(to much money invested in it now) here some photos of first grow in soil, yielded 9 oz dry weight from 4 plants. A couple critical purples, purple sunset and a Bruce banner.
