Because they said so, lol.

I e-mailed them (Fox Farms) a couple of months ago asking if I needed to add micro's seperate from their formula. They said it (the 3-part system) has all the micro's you need, but they were almost too careful not to be specific.

So my thoughts are that it likely contains all of the micro's for throughout the grow. Would Kinda explain why using Big Bloom at half-dose is working so well for me, but since it's organic, perhaps it is just build-up if used too liberally. (like...at recommended dilution, lol)

I guess I could shoot 'em another e-mail asking more specific questions, tho.
Rusty Trichome Reviewed by Rusty Trichome on . Yellowing leaves. This starts to happen after about two weeks in flowering, see pic. I started using only RO water (thinking nutrient lockout) and minimum dosage of Tiger Bloom (2tsp/gal). The leave on the left is from 2 wk flowering and the other is from an older almost done plant. I still get decent buds, but something isn't right. Can anybody identify problem by looking at leaves. The room is not hot 75-85, and i only use dilute nutrients. Peters 20-20-20 during veg (about 1/4tsp/gal). Thanks Rating: 5
