Hermaphodites, Genes & Purple

I have a question for you advanced growers:

I am growing Blackberry currently. I want to see some purple in the buds. My basement temperature is currently 50-55 F. I am about to try to flower my clones next week in the basement. Now....Is there a chance my clones will turn from proven females to hermaphrodites? Thanks for all your help.

yes, if you stress out a plant enough, from lack of light, food, excessively high or low temperatures etc... it has the chance of turning hermie.

I see. I was afraid of that. Well maybe I will put half downstairs and half in my regular set-up. I am in experiment mode currently. No guts, no glory!
