Would like to see the whole plant and know your EC level you are feeding at and ph. You can lock Calcium out if your feeding to much Potassium.
I've done many grows in many different systens now and used to get a calcium defiency nearly every grow, that was until I used cal/mag as a spray foliation & now I don't see the calcium problem anymore since feeding through the leaves.. Drench feeding Calmag plays havoc with ec & ph as I found out for myself..
I would never use Ro water as I see it as more problems than what its worth.. Having to make sure you add every element the canna plants needs & the nutes don't contain all the essentials.. More chances of running into issues.. Just use coco & spray Calmag in veg and once thought stretch & that's all there is to it.. too much faffing around imo.
