Are they outside?
There is a bug in the 2nd pic.
Not sure what the issue is, looks like a fungus to me but IDK, others will chime in.

Did you buffer your coco with calmag? Cause that’s a calcium deficiency. If you forgot/didn’t know to buffer you can just add calmag to your feed, make sure it’s the first thing you put in your water though.

I gave it them for just a few watering but that was a few week ago the calmag I have has nitrogen in as well should i just put in the recommended full dosage and then just add the a and b until desired ec

Hey man, how's your plants doing now? Can you update with photos and let us know what ya did to get them back on track? Was having the same issues a while back and I increased the calmag to full strength and issue eventually went away. I'm also using canna coco nutrients, this is my first time ever using them.
