Soil was buffered in CALiMAGic 1-0-0 at 5mL/gal (75mL total per 2.5lb Hydro Crunch Coco Coir) for ~12 hours, then flushed.
Kept soil moist, not too wet.
Slurry test on day 3 showed soil pH of 7.0
Day 4 was the first day I watered, just to keep soil damp.
PPFD double checked, lowered from 350 to 250.
