Getting cal & mag issues using the HD with a couple of my girls. The HD is 8-5-13, 10% Ca 2.5% Mg, I was wondering why the K was so high before I started using it knowing how coco loves to bind Ca/Mg and give off a lot of K. What's a good Ca/Mg product to use? I have GH Calimagic but it has calcium carbonate as the source of Ca which I'm thinking may be a lil to late to use being slow to release and all. I'm at 28 days bloom, will using something with cal nitrate in it keep them too green?? This is my 1st coco grow and things are going good other than this, if I can't figure this out I might just have to switch nutes to something with a lower K ratio.
