I guess this is where I went wrong last time: I started the grow 12/12 from seed using the HPS light. Too intense and too hot. I then switched from HPS to LED and I hadn't cleaned the cabinet of stray pollen from the prior grow...

I mean look at the Magic bud sprouts now, I germinated them in soil, from sowing day I had them on 24/0 for 7 days and 10 days into12/12 look at them now! (17 days total from sowing).
