Had some major dryness issues. RH around 30%. Some Seedling’s leaves were twisted and deformed a bit. added humidifier and brought to around 50%. Instant improvements. Being a noob, By day 12 I realized the roots were drying out which was the main cause of the freak plants (weird thin pale leaves on some, twisting and deformities on others). I was watering very lightly and about once every 48 hours - to the point of almost complete dryness. Not the best for seedlings I guess. On day 12 I top dressed a handful of worm castings, and watered with 1:50 ratio of Marphyl phytoplankton soil conditioner giving a decent weight to the solo cups. Planning to switch to 12/12 at 3 weeks of veg growth to find and cull the males. Hoping after a week of 12/12 I will find the males / ideally identify females and remove the dudes. I am planning to add another shop light for this process (or ASAP) with fluorescent bulbs at 3000k or 4100k. To add a bit of warmth and a (somewhat) more orange spectrum to help trigger presexing. So that will be 2 x 5000K LED 2 x 41000K CFL Both 4 feet long in shop lights. Will it work? Will it take longer than a week to find the males? Not sure. But I will find out. Jan 14 will be the 2 week mark.
