I was using straight R/O water with no Cal Mag or anything added for the first 2 weeks. Pretty sure it stripped my plants of their minerals. I added Cal Mag last watering, and thinking I will be adding at least a half dose every watering moving forward. Thoughts?
@Angrybird Growing I think you're loving them too much. RO shouldn't "strip nutrients" in that soil. 1200+ ppm is super high, especially for their size. It's very possible you've over watered.
It's been a while since I've done liquid synth nutes but I'm thinking at that size you could be down at 400 ppm or less and be just fine.
They should stand up to some drying out and it may even promote root growth. Try to water the medium more evenly, not just around the plants. You'll water less often then too, it'll keep a more even moisture.
Do what you can to keep a more even RH. At this stage they'll benefit from higher humidity, 67 is good. They're small so they're not "breathing" a lot. Don't worry too much about fresh air exchange, the humidity is more important.

I think I know what I did wrong now.
