@Pauline, harvested a few of these done a fair few RQS with bio throughout . In 12l pot
An some in a mix I made up in 30l pot they all stacked up well none were purple?
Was under HPS
They did like food half dose of bio . Full dose of ionic different soil.. most took 10 -12 weeks trichomes all cloudy never see an amber one...
You should listen to the other guy though his been helping you through. I don’t do EC etc just PH 6.2 6.5 . After nutrients . I’m new here just what worked
Plant seed in light mix in-the middle of the pot all mix outside so the roots grow into it after a week or so.... . AK gave twice as much yield as others...
