Nope no calmag needed .and I use coco DTW & RO also . I've been running a few of dutch growns strains with it & they are calmag hogs !!! & the only thing i've noticed was a tiny yellowing on some new growth which could just be fast new growth or a slight mag deficiancy ... very slight .... I'm sure Bio master will chime in soon .... he's been doing side by sides with different nutes & he seems to love this stuff as much as i doSo here's the deal, I got their ro formula and I'm gonna run it head/head against Maxibloom. This will be in coco amended with perlite.
Normally I use tap water but since I'm trying to avoid as many variables as possible I wanted to run RO water.
Going to run my tried and true Gorilla Grape, a strain that I've been running for over 2 years now and one that I know all it's nuances.
Gotta run to the shop and grab a ec pen...
So, first question...Anybody having to supplement calmag when using the RO version?
Btw, I will document this side/side for all to see

good luck with the side by side . link us to the thread about it so we can see the results . thanx evlme2Finished several side by side testing and Veg+Bloom keeps blowing them away one after another.....the latest testing was V+B up against the new Cultured Solutions by Current Culture the people that make the UC system.....this stuff is supposed to be especially for RDWC systems like the UC.....V+B works better! The guys at CC could learn a few things from Hydroponic-Research that is for sure!!
