Started out in the beginning as everyone does just using plain ol
Botanicare CalMag. Then switched to a different one, then switched to
General Organics CalMg+ (which was very solid too), but after recommendations from Growmaster- I switched to Calpex.
Difference was definitely there but probably not what you are expecting. The difference wasn't as much in finish of product as it was in the elimination of any "cal/mag" issues. Using all of the calmags prior, it always seemed to be a process of dialing each plant individually for its
calmag needs and if they didn't get what they wanted/or too much it was evident. After switching to calplex I have seen "0" and i mean no "
calmag" deficiencies or issues with either component. I was able to go from levels around 7-12ml/g on some strains with
calmag, to no more than 5-6ml/g max on ALL plants (no need to vary and im actually working on how little is actually needed to achieve same results...so far I haven't found the low point). Even after switching over to coco last year, which i always hear
calmag horror stories about, I'm using way less. Plants are always green, lush, and no deficiencies.
IMVHO, I think most "def/issues" are mag surplus which causes the same look as defic. GM said most bases have plenty of mag and why you use calplex alone, ive now run calpex with about 4-5 different nute brands (AO, GO, Roots, Canna AB, AN Sensi/3pt/Connie) and all have had pretty much similar results none with cal problems. Probably the closest to any def was Canna cuz i think levels are too high for whats needed.
Just my opinion. Have tested it a decent amount tho.
