Dudes!  I need some advice…

I’m currently on my first grow, 14 days in.  Sour Apple Autos from Humboldt Seeds planted in 3 gallon fabric pots with roots organic soil.  In a 4×2 super closet, Kind X330 LED lighting.  I’ve given 2 waterings of Recharge, and other than that pH water only.

I plan on top dressing Gaia Green all purpose around weeks 3/4, but I need to know…Do I need to add Cal-Mag?  If so, how often I’m trying to go all organic and KISS method, but need help!

Thanks, and grow happy!

    Do you know what your water starting ppm is? I guess that would probably be a starting point and deciding whether it was critical or not. When I make big big pile of soil that has the time to compost, I use dolomite lime.Oyster shells I think to probably have calcium. That stuff takes a while to be available though. I use two mil per gallon every watering. Whether I feed or not. My water starts out with zero ppm. I’m not organic. Hopefully that’s helpful. I did not research any of that. Fact of the matter is you could research it just as well. I feel super confident though. Noticed nobody had commented and figured it was better than no help.
