Poeple think Jacks has too much K with its 26%, i run a 36% Mix and have no Ca Issues at around 2:1 K/Ca Ratio, in Coco.
After a while of feeding theres so much Phosphate Binding in any given Substrate that what you think you are feeding isnt what Plants have actually availible for them.
How about the University of Florida for one? Even then, it still needs more Ca. A couple of the guys are running even higher Ca using a good chelate and it is much better than the Univ of Florida attempts. Of course you can't get close to the ratios needed in the "mythical soil". That is what makes hydro so lousy. Hydro looks great, often smells great, but the terps, oils, yields and at the end of the day, smoking quality, aren't there IMHO.
Sounds like you need to understand electrical charges a bit more. This crop will tolerate a lot, that is quite evident and if you see issues, well, you missed the boat anyways. Saying you don't see issues doesn't mean much. If you EVER have a calcium deficiency, there is NO catching up. So far, EVERYONE has had a calcium deficiency!
