I started my plants in 3 gallon pots in coco, but was only giving 1-1.5 cups each of fertigation each per day. Reading more tutorials, I realized that i should have been going to run off (10-20%). I started doing that on day 7. The runoff was acidic (~ph 5). Should i flush each pot until a neutral ph, then re-fertigate with nutes to runoff ( watering a couple inches around them?)
Or can i rely on fertigating to 20% runoff to bring it down with half strength nutes? I notice theres even a bit of white powdery stuff on the top.
