Very sweet lookin plants.

Couple questions for you:

I've read that you can take clones 3wks into flower but it seems everyone does it before flower, is it ok to keep taking clones?

My plants are finishing week 4 of flower and some of the shorter, bottom branches are hardly flowering at all. Are these prime candidates for cloning?

Last but not least. Do you're clones ever develop purple stems before rooting? lol
