Yeah I had the same issue with my first plants in coco. All I knew was that I wanted to try coco but I was doing 1/2 strength off the bottle nutes and didn't even really know what N-P-K was. I knew I needed cal-mag but didn't know why either. It's essential in coco and seems to be the #1 problem. The #2 problem is not charging coco when transplanting and the plants slow way down until the coco gets fed a few times. Same concept.
You're always welcome for the info, now put it to good use! Btw I am headed to your journal to take a look. Hope you don't mind!
Thanks again Ase!! I have written this all down. I even drew a diagram of how you transplant using the small pot in the middle of the big pot! Lol
