Thanks Chaos. I'll get a feel for how the MC works under led this summer. In my experience, every nute line I've used under led has required a supplement of Cal/mag so I guess I shouldnt expect MC to be much different.
I've had a great experience with it in municipal tap (mine runs about 110 ppm from tap & pH of 6.8-7.6 depending on season) but have seen others mention heavy pH drop in RO. I believe it was discovered that there were heavy pH drops due to bubblers or something along those lines?
@rkymtnman @cat of curiosity @GreenleafNutrients can likely add to this.
