I see plenty of stuff near the bottom you can safely use for clones with no loss in yield. Your plants are developing one main cola. The stuff at the bottom won't yield. I'd take 2-4 clones from each of those plants.. by the time these 2 are done, you'll have the next batch ready for flower, so your total yield would be many MANY times what you're gonna get w/o snippin'. Just my opinion...and I have lots of opinions hehe.
