Greetings,
My bag seed seedlings won't grow, they just turn yellow. I am growing in DWC with rockwool cubes. I ph'd the rockwool prior to putting germinating seedlings in, the cotyledon appears and everything stops. They are in a grow tent under a mars300 LED as well as a CFL. I keep my ph at 5.8-6.1 and ppm is 250 without nutes (filtered water and let sit for a few days) cubes are moist not soaked. Tent temps/humidity are good. What else am I missing? I've tried no nutes, few nutes and lots of nutes and nothing works. Any advise? I'm using DNF Grow A&B.
