Is it possible to overnourish with just Stepwell's living, super soil (and earlier, a bit of Fox Farm Happy Frog) with only reverse-osmosis water? I haven't added any nutes. Sorry, if I sound like a total noob, I am. This is just my second grow.
I've heard that using reverse-osmisis water can lead to cal-mag deficiencies. But I've seen what looks like it might be nitrogen claw on some plants. Can it be over in some nutes and under in others?
I went the organic soil route to make things simpler, but it's not so simple still. I'm going to try somehow to correct my low-humidity issues asap, as well as use a different soil when I transplant to larger pots.
There's a place near me called Pagonis that makes super soils. They use no peat moss whatsoever and their base is 40% EWC, which they make on their own earthworm farm because they really focus on microbial activity. Maybe I'll have better luck with a better balanced organic soil. I've heard that lately that many are way too high in peat moss to cut costs.
