I don't use coco so not expert advice is gonna be given. Just basic.. If you have a ph meter then flush til run-off is 6.8 no lower than 5.8 or you'll have to use your ph solution to balance. You should be using ph'd water for your flush.

I would take my meter and see what the ph of the coco is and go from there as to when to feed again. You don't wanna burn up any of the gurls!
