Week 4.5, after 3 feedings, every 3rd day after defoliation, I flush with only phd water, molasses, and mammoth enzymes. 3 days later I dial back the compost tea plus Epsom salts to 800 ppm and flush again. These are in 20 gal smart pots, and I’m making sure that each pot is leaking a good amount , about a gal, per pot. I’ve also lowered the ppms of co2 during this time to 800. 3 days later I begin again raising the ppms of my nutrients. I like to add humid acids, extra cal mag , and full on molasses. Ppms are now 1000, ppms of co2 are 1200. This next week I’ll raise the temp in room to 82 during day, and 65 at night. This might seem a bit much, but in my experience a 15-20 degree dip works great as it is gradual through either.
