I'll count this as my first grow, since my "testing the waters" grow was a male. I germinated 3 feminized Northern Lights, all 3 looking good so far. I went for a rather resilient plant for my first go. Growing in FoxFarm soil, 300w led (have another for once they need it). Currently using my 2x2, but have a 4x4 when they're ready. Timer set for 18-6. It's been a little over a week since seed, and here we are. ^ Is this purple on the leaves normal for some strains? They're not getting anything but H2O, air, and light. 2/3 have this going on. Temps at 78 lights on, 69-70 lights off. Humidity 50% lights on, 60% lights off. Cheers!
