What you guys think? Magnesium and/or Iron deficiency is the common answer here when there’s yellowing happening with the green veins. And when I see this it’s always at the top leaves when it appears, not the first time with me. The first was when I was in flower using synthetic nutes, never really recovered from that grow. Now on this grow, where I’m experimenting with organic dry amendments (with FoxFarm Soil) 5 weeks into Veg… it comes up again. o.O I was under the impression that in organic grows, if you took care of the soil, the soil in turn would take care of the plant. Little confused right now. My dry amendments are (all natural) Earth Dust Base & Earth Dust Boost, some Organic Kelp Meal, and Organic Langbeinite.
I water just enough to keep the soil moist and read an article that if you overfeed Potassium, the plant can absorb more of that in place of the Magnesium, and I’m really wondering if that’s possible in organic grows.
Another angle, or theory of mine is the possibility I just didn’t add enough amendments. and or I somehow overwatered these ladies which is easy to do in potted soil grows. Lot to think about here.
What I’ve done so far to help with this (recently) is top amend with 2-3 cups of Earth Worm Castings and a dose/watering of the classic RealGrowers Recharge (ultra concentrated microbial superpack).
I don’t think it to be from any issues (light stress) coming from my LED lighting as they are at 60% and hovering above at about 20 inches from the ladies
My question is, ride what I’ve done so far to see what happens or is there something else I can add or do? Am I out in left field with my whole thought process here?
