Hulk, I switched soil.  I’ve used only fish shit and Aurora Innovation Cal Mag to adjust my RO water ppm to 90-110 with a ph of 5.5-5.7 for veg. Pushing ph up for flower.  It has two parts, vegetative soil and a top dressing for flower that says to apply 1.5-2” thick 2 weeks before the flip.  I’ll send you all the info on this soil.
