Now thats whats up! The odds are very high that a male/hermie is pollonateing the plants.Yeah man that stuff happens. Are there any males around possibly spreading pollen?
Some strains will turn purple with out colder temps. The colder temps helps a little to bring out the purple.i just picked up a clone that is like a little baby and its turning purple. so i guess it can happen at any time. i thought you had to introduced cold cold weather to make it purple but mine are in the california sun turning purple
