Day 136: Flower day 68: After taking some detailed photos and inspecting the trichomes, I think I am late starting my flush. At the recommendation of others, I flushed approximately 20+ gallons per plant and brought the runoff pool in the tray down from 2800ish to 300ish. I couldn't seem to get it any lower, so I assume accumulation in the drip tray over the grow period is adding to the higher readings. I feel much better having flushed.
