White Widow Supreme (AMS) trees to be.

Unfortunately the worst grow I’ve had so far due to cold temperatures. I added a small space heater a couple weeks ago but still can’t seem to regulate the temperature. Disappointing to see them so weak, stems often purple and really short overall. It’s not at all clear that the six are going to produce anything of consequence. Anyway in terms of care, they’re getting fed once a week and pH adjusted watering the rest of the time, about every other day. Some leaves are turning yellow and some with splotches. Looking up online it would appear to be a calcium deficiency but that doesn’t really seem likely. I think it’s the cold. Giving them TLC through all of this, daily care and special attention to over/under watering. Not sure why two out of the six in particular are so droopy. I’ll chalk this up to the cold too. If I grow in the winter I’m gonna have to master this temperature in the basement question. For now, I’ll just keep on with the six & see what cannabis plants growing at 16-18° end up looking like. Growing some eggplant in the tent after germination upstairs so that’s pretty exciting. Peppers to follow by the time this poor grow is done. Thank you for reading!
