Cheers dude, im already using rhizotonic, cannazym, along with canna a and b, my plants are like 11 days old so im just giving a 0.7 ec mix with n ph between 5.8 and 6.0... ive been in 2 minds wether to start with the cal mag but left it as it raises my ec but my waters very soft at 100ppm and thats european measurement so were talking just over 0.1 ec so it makes sense that it needs cal mag especially in coco..
My course of action will be adding cal mag to my tank, and maybe foliar spray my plants once a week with vulvic acid to help with the intake of nutes just incase..
Appreciate the advice...
