Hey mate your plants look good. Im using the coco coir with the same nutrients from canna, do you have a spreadsheet or are you mixing it with a max ppm in mind?
@MF_Shuriken, Researched each nute, then created my own cheat-sheet!
I'm no expert, still a newbie, but, as for PPM... they are all just guidance, because each plant is individual. Pay attention to the leaves, they'll let you know where your at! 😉
