Cherry pie

You can defoliate as late as week 4. At this point since you already lollipoped them i would just remove leaves that are blocking prime bud sights from the light. Hope this helps

Total BS as far as cannabis is concerned, so is adding ice. Colour change is usually a genetic thing, generally induced by having night temps 10-15 degrees Celsius lower than the day time temps, although there are a number of purple strains, mostly Pakistani Indica in descent. Cheers, Organoman.

Your still a few weeks away from harvest, they will change soon. Give about 10 days on nutes and 2 weeks ph water.

Damage is done. Take all the time they need. You will have seeds. That can be a bummer. But don't look at it as a bad thing. You have an opportunity to use YOUR genetics! Do you know who the father is? I have had some success at taking "accidents" like this and breeding really strong, good-producing plants. Granted this harvest may not be what you expected. Seeds are a pain to pick out of good buds. But the next go-round you will have plenty of planting material....and hopefully a new stain! Good luck! 😬
