bickey, all of your plants look great - sweet purple room! As for your questions, I probably don't have the answers, but I'll throw out some suggestions.

For your mystery purple, do you think you could tie some string to her uppermost stalk and tie her down without breaking her stalk? Also, does she have quite a bit of lower bud sites? If she has a bunch of lower bud sites, maybe top her? Since she has been flowering well for awhile, I don't know that I would throw her outside; or, I would wait until the fall solstice when it's 12/12 outdoors, then throw her outside.

As for your clones, I have never messed with clones, but that won't stop me from putting some thoughts on the table. How are their roots? Did you trim the fan leaves back any? Maybe the roots cannot support a lot of leaves (being the reason for the last 2 questions)?

Hopefully you'll get some good advice in here. I doubt my suggestions will help all that much, but thought I'd throw something on the table - maybe someone will come along and correct me, thereby helping you out? I hope you get all of your issues sorted, though in the long run, they will probably sort themselves. By and large your grow room looks pretty flippin' amazing, my friend! Be good out there!
