NLxBB cloning issue

Ok, so i have some plants, when they hit flower, my Northern Lightx Blue Berrys got realllllllly awesome and pretty and smelly and just an overall great plant. However, I didn't get any males, so what do i do? I know I have to clone, but these babies are in their 4th week of flower and from what I understand it won't clone well.

Should I harvest carefully....throw it back in veg light and then take clones?

Should I clone a sparsely budded branch now?

I just want to make sure I can keep this strain alive because, even though I haven't smoked it, i can tell its gonna be awesome. HELP ME GUYS! I have plenty of plants to make clones.....give me some advice!

Sometimes taking clones that late into flower can cause some mutations in the off spring IMO. I have herd it before and experienced it first hand. I took a clone from a girl that was doing so good in flower that I wanted to keep her line going and I cloned her and she became nice and branchy so I was keeping her as a mother. Well, what do you think happened, I took clones from her on 3 different occasions and all of the clones from her went hermy on me. Luckily I had other things going so having to toss the 16 flowering clones didn't hurt me too much.
I would just snip the buds off of the branches when you cut her and reveg her if you have the time and space. It will take about 30 days of 18-6 or 24-7 to see new growth.
This may not be everyone's take on it, but it is what I would do.
