Day 18 here for TrainWreck. Yes, its bad. Clear underdevelopment, and pH problems. Nute problems, whatever. All on account of the basement temperature dips and just untrue core temps. Yesterday I diverted my basement furnace output directly into the veg. tent and installed a thermostat. I can already see a difference despite the haggard appearance. I’m still dialing it in but at least now the temps are consistent and warm. Hopefully its not too late.
