Mayhem F2

I got some of these free with my last order from doc C. Russion indica X Blockhead.
What can i expect from an F2 strain? I know theyre not as vigorus growers as an F1 but i understand that a few of em might produce purple buds and leaves is this right?
Also do all F2's produce pink pistalls?

 

Blockhead (spice of life seeds) is highly rated for it's potency and it's leaves and bracts can turn purple in lower temps. I know nothing about the Russian Indica.

Well made F1s will be fairly similar to eachother and will reflect a stable (in this first generation) cross of it's parents.
F2s often retain some good traits from their parents/grandparents and often produce some good plants, just that there will be more variation.
No, not all F2s produce pink pistils.
