In my view, feeding mor often increases oxygen and fresh nutes to the coco like in hydro. That said, make sure your using less ppm. Unused nutes will build up if your not feeding enough to get some runoff. I go for the pot/container to feel heavy. Sometimes I let it go a day before feeding to get the roots moving along, through out the whole grow, and so I can gauge by feel how much they are taking in or is being evaporated off. The key to coco, is less is more. Either way you feed. Heavy 1 time or mini multiples. I've had to flush for weeks to get most the nutes out from going to heavy. Even then I'm not sure I did all the way.
Also, coco breathes well so there should be plenty of oxygen feeding once or many times.
Uh, I think that covers ya.
