I use coco in pots. I always feed, never just water, until time for final flush b-4 harvest. I feed/water when the pots are light, about every 2-4 days. I always feed/water to run-off (10-20%) I write down all activity. I feed all the around the pot, not just in the middle. This method is based on what my mentor has developed over a long, very successful career, along with a lot of research on my part. I use AN pH Perfect nutes (no negative remarks please). Our water is glacier melt and is as close to pure as you can get naturally (ppm of 12!). I have thought about a 2 feed/1 water schedule, but am not sure it would help at this point. Thanks in advance.
