How does she look? Just keep going the way i am with her? 2 out of 3 are as strong as her. The weak one only had one baby leaf. I burned her by giving her the same food. I washed it out and shes recovering and new growth looks good.

Looks very healthy but why does everyone think they need perlite . U don't need that if u r using canna.. canna states to use there aqua line instead of there coco line if u r mixing coco and perlite.. otherwise ur plants look healthy af

Yea it was hard to decide. I kept finding conflicting results. Now i know, thanks!

Hey man no problem..ya I know there are so many conflicting results .. but u know what ur doing what works for u and that's great I was just putting my two cents in.. like I said she looks absolutely beautiful great work peace bro
