Hey buddy. Coco is a nightmare at the beginning. I had like 70-80% run-off from 300ml but as the r9ots grow and the coco itself will hold water better after time, my zkittlez can take 2.7l of water now and only a few drops come out, and say if I go over the bank breaks and I lose about a l of fluid. But yeah with coco. 5-10 waterings a day. It's impossible to overwater coco plants, well nearly impossible unless you have very bad drainage. But yeah, 5-10 waterings, I myself did a mix. Half nute feeds 1 nute feed then 1 water feed. Or you can just feed everytime with a 1l bottle but make sure you do q hard flush, meaning lots of run-off to flush out salts/nute build up 2 avoid nute lock. Good luck pal.
