some times temperature can do it too. I read someones grow log once and he used a similar setup to you. He claimed that the mixed spectrum made some of his plants turn purple and they had never done that before. This was a strain hed grown from clones for a while too so its not like its a different phenotype. Maybe youll see something similar.


heres a pic of one of my buds. This was a couple of weeks ago and its getting flushed right now.
