    I had that same problem & I used green magic 1 a week in veg and they went from what you got to dark green! Its gdp so keep that in mind but I spayed my sativas with it just cuz and had no issues with them.

    Well I you're growing in coco I believe your ph should be more in the hydro range 5.3-5.8 but I could be mistaken as I've never done coco myself

    On the nuts it says 5.5 to 6.5 do u think taking it down will help ??

    Yeah I think 6.5 is too high for coco but you should do some reading in the coco coir section of hydroponics. A lot of good info there.
