You still seem not to be using the FloraGrow and I can't understand why... but she's looking quite hungry at this point... If you have a ppm meter, when you feed her, the ppm should be between 550 and 650... and it should remain there for the rest of the grow. You should be using 1 part FloraGrow, 2 parts FloraMicro and 3 parts FloraBloom ...
And growing in coco, as I've had a friend describe it to me, is growing hydro in soil... so it must be kept wet... The ideal routine is water/feed/water/feed -
Good luck...
