Alright guys! I have a question and need some help from everyone. I know I have read that you can use the Canna over and over, however, I am experiencing some problems lately. And when I compare to pots that are growing in new compared to old coco that has been re-used I notice a difference. The stuff that is reused more seems to develop some defficiencies that are very hard to pin down and remedy.
Has anyone else experienced this or have I forgotten something about the Cana losing it's buffering ability? What is some other past EXPERIENCE?
I never flush with plain tap and use Great White for the beneficial bacteria. So what do you all think?
BTW, It seems to be a sever Pottasium defficiency. Browning on lower leaves, severyly. No matter what i use.
