Canna Coco Growers, I need help

Take a look at my pics, there is a problem with my plants but I dont know what. The bigger water leaves look like they are browning, like they are getting burned or something.

it almost looks like ph, is it a rusty color? can't really tell. if it is just yellowing i think nature is taking her course. those are some sweet looking plants. good job!!!

what are you feeding them? i'm doing my first canna coco grow, i love it so far.

good luck, kevin

I too am on the canna bandwagon. I use canna coir, hygrozyme, cal mag, sweet, pk 13/14, and the canna rhizo product when needed. Im real happy so far. As for your problem Im not too sure buddy but your grow looks great. I would just keep an eye that it doesnt get worse.

These are the nutrients I am using. My plants still have the "rusty" color to the leaves. Other than that they look great. Right now I am using the boost and PK13/14 for just one week and the buds are doubling in size. NO CO2 used. I love me some canna coco. The boose I will continue to use through out the budding cycle.

Here is a few more pics

with the rust color i have always found it to be ph. just check the ph of your run off and adjust as needed. i've heard that coco is real forgiving/ easy to fix.

got the same prob. I have ruled out everything. is there coco in your medium? then it is fucked. I am mean any at all. a pinch for bad luck. lol. JK!!!.


I got the rust. i have never seen it before. i got omri certified coco. I am not using any nutes on the current seedlings. the other had some bmo organic nutes. i thought it was ph. i thought it was a bacteria explosion. i though it was gnats at the roots. it might have something to do with heat. maybe something else too. together they screw it up. that and maybe my coco was unwashed? even tho it is a small bit of the grow and the rest is ocean forest and organicate aeration mix. idk, but your plants are awesome.

not to offend any coco users, this is my first time adding coco on its own and i want a coc grow so bad, but it might be my bad luck and ocean forest it is.

This is the coco soil I use. Its 100% coco and thats it. You should you this soil only and not mix it with any other kind of soil. The coco its self is nutrientless meaning you HAVE to add the nutrients. (use the ones I have in the pics, except there is one thats not in the pic, its called Canazyme) This is the first time I have had a problem with the plants and I have been growing with coco for a year.

What strain? I have G13 BB and its been hell on the cal/mag.
