Floraduo and Coco

Does anybody use floraduo in coco, if so how much do you feed them? Ive been giving them 1/4 of strength , and was wondering how strong i should go with it. They look good now, but that seems really weak. Any input is appreciated.

Here is a pic, maybe that will help.

No comments at all, well ill keep on doing what im doing.

Yea im using floraduo i was uder feeding at 1st but i changed the feed schedule to bout 5ml of both in veg then 10ml both in flower because the A has the cal nit in it and also throw 5ml of sensical grow in now they almost to dark but not yellow lol anymore

Always always always always "under" feed. Looks good so far, just remember, all it takes is one over nute instance to ruin all your crops, so better safe than sorry.
