Is it possible to LST in flowering since 2 weeks?

Hi,

I am first timer and just learned about LST on the forum. I was wondering if I can still try it on my females...Also My plants have been under flowering cycle for two weeks and the girls are showing little white hair.

Is it possible to clone at this point.

Thanks

LST is about getting more bud sites on a vegging plant. It will be useless in flower, since the plant will not create any new bud sites while it's in flower.
It is possible to clone a flowering plant, but it is not the best time to do it.
A clone from a flowering plant will take a long time to revert back to a vegetative state. Some plants (autoflower strains) will never reveg.
