Review: Organic Cal Mag - Took about a week or so before it arrived, but that's ok. So did everything else I had ordered from other sellers. Now, the bottle looks smaller than I had imagined, but it was the right oz's. Anyway, I really love this so far. 3/4 thru my grow and everything looks beautiful and healthy. I don't say that lightly.... I use just 4ml per gal of water for almost every watering. I will gladly pay the price and order another one. I'm not gonna get the big bottle because this 8oz will carry thru the whole grow. I have new fresh stuff for the start of every grow ## Features - ORGANIC CALMAG FOR ALL PLANTS: Organic Calcium, magnesium, and micronutrients micro-chelated with Organic Acids for bio-availability. - PREVENTS COMMON GROWTH DEFICIENCES: Apply CalMag in every stage of growth for strong stalk and leaf health.
