Would you say there is a problem here? Plants seem to be happy and progressively growing. I’ve noticed over the past couple days the stems turning purple.
Nothing to worry about! Nice grow you got
Some strains have purple stems, I can think of a hashplant that is very purple. Its primarily an indica trait though, never seen purple leaf stems on traditional sativas?
Most led grows have the purpling. Mine does.
I believe that was from water splash…at least I hope
