I have this problem with yellowing leaves every year- usually after flowering when I switch nutes but this year it started early.

Conditions:
Medium- Promix BX (General Purpose)
Nute- Botanicare Pure Blend Pro Grow 3-2-4
Feeding Cycle: Every 2 weeks
Soil pH: 6.5 (tested today)

Same issue I have but I also have copper colored spots and same "soil"
I'm trying PH 5.8-6.0 with calimagic (cal mg) and it seems to be working

Promix PH seems to be a hard subject to get an answer on but I've found ppl say 6.0 on a different site Google soil and hydro PH chart for cannabis and go with the hydro side and favor the higher ranges
