Haha I'm sure you will get lots of help just try to be a specific as possible with questions the lack of specific question just invites trolls. I grow in coco I use jack nutrients 321 recipe full strength from clone to harvest I would highly recommend Jack's it's as cheap as you can get and grows as high quality as anything else. As far as how often to feed I'm sure you will get a few answers but that's more of a trial and error thing every strain grows differently and you didn't mention how big the cubes are. Watering strongly depends on how big the plants and cubes are.
