Howdy
Yea I guess I know that but what about the gap between Nutes in,Nutes out
So if runoff is 6.45 but in it was 5.5 so the gap of .95 how low do I need to be and for how long to see the root zone get to 5.8
Like how often do I water Coco,every hour or 3 hours or 8 hourly?????
Gee I hope I'm making sense lol
