They just look purple. I am assuming you have full spectrum on you light. Mine look purple because of that. If you take the plant away from light the purple is green.
I have 5 White Widow autos. You just have th let them be. They are a very fussy strain. After two fails left these alone. I alternated nukes then water.I am now flushing on my eighth week. Waiting on pistals to turn amber. Then will put it in darkness for 72 hours. Take them out on third...
Yes. I am prepared to do that real soon. My plants into 8th week. They say by complete darkness for 48 hrs. No light anywhere. It shuts down thinking that it is becoming winter and buds swell an THC gets stronger. Will let you know if it works.
