Your girls are looking great--

and used

Trio before with WW grows (tho' a different breeder,) I suggest you think about adding some Cal-Mag Plus to your feeding regime particularly now. I don't know whether its the

or the genetics of WW (reported on other forums to be magnesium hogs) but both of my grows went through mag deficiency around Day 35 or so. Regardless of my experience, I believe a lot of experienced growers strongly recommend Cal-Mag as a preventative additive.
