White bumps and purple top
Stem have white bumps and to leaves are turning purple I’ve started using cal mag hopefully will help but please any advice on how it’s going this is my first ever attempt
Your plant looks happy and very healthy to me. The white bumps are perfectly normal for a cannabis plants' stem. The slight purple colours are also completely normal - nothing to worry about. Cal/mag is only really needed in extra quantities during flowering. Any decent "grow" nutrients will have enough cal/mag in it for healthy vegetative growth. Hope this helps.... Organoman.
