yan420answered grow question 8mo ago Hey man, donāt know that soil brand myself, but that yellowing between the veins on new leafs looks like early mag deficiency.
Even with pH in range, things can still get blocked. Tap waterās usually got calcium, but not much mag, and too much cal can lock it out.
Iād try:
Dropping pH to around 6.2 for a bit
Slight bump in cal mag
Maybe a foliar spray with Epsom salts before lights out for a quick fix
If new growth comes in clean, youāre all good.
