cloning from flowerin

ok what i dont understand is if i start from seed thay veg then i want 2 find out the sex so i flower then KILL the males and go back too veg too clone some help plz

What you want to do is clone BEFORE you flower. You will not know if your clones are male/female yet so make sure you know which clones came from which plant. If you find a male be sure to kill it and all the clones you got from it.

thanks so how do u make mothers plants

Mother Plant is simply "a female plant that you have taken clones from."

could i veg,flower then veg then colne then that way it will still grow
will that fuck up the plant

It is possible to revert back to veg. after flowering with a normal plant.
However, a clone that has not yet rooted might still be under too much stress.... It may not survive but I really dont know because I havent ever tried.
