I'm growing a couple of sweet seeds skunk auto, two hawaiian hazr, and one strawberry blue in coco loco by fox farms. I called fox farms and they told me that its basically a hybrid media with coco and hummus and to make sure that my ph is between 6.2-6.5 and i should have success. I was at my local hydro store yesterday, where i bought the coco loco, to pick up some cal mag and mentioned to the guy that my ladies looked a little small for ten days old and he told me that the coco loco was inert and to introduce some 1/8 strength nutes. Does this sound correct? I have fox farms grow big and now some cal mag. What do you guys think?
