need some help please

Hello, I have a few questions I need cleared up. First let me get you familiar with my setup. I have three females 2.5 ft tall, growing on soil under eight, four foot fluorescent fixtures on 24 hrs a day. They have been growing vegitatively for two months and I just switched them to 12/12 two weeks ago to show sex. Origionally had seven plants, four were males taken out of the batch and put under seperate lighting. I want to take clones off the females eventually. Can I put them back to 24 hrs a day setting them back into vegitative state? One of the plants was ahead of the others and has small buds growing. What do I do about that? I want clones off all three of them, being that they are seperate strains. Someone please walk me through this one. Oh yeah, can i get any bud from the males or should I toss them? Thanks for reading this and any help you can give would be priceless!

If the males were takin out and put in new lighting in the same house or somtimes same neiborhood you will have seeds in your bud.

I dont like to stop flower mode due to the hermy factor. clones should have been takin before 12/12 was started
