No hairs on my top colas?

for some reason 3 or 4 dont have any hairs on their top cloas. I dontr see any burns, at least not recent ones.

Ill get pic tonight, but if i have ended up burning them should i just leave them or should i cut them off and cut my loss?

How long have they been on 12/12? What sort of light and how close is it? And photos are definitely going to be vital to answering your question at all. Sometimes it takes a week or two to see significant "hairs" (pistols) forming. You shouldn't cut the top cola of any flowering plant that you want to survive.

The ones that burnt were under a 1k Hortilux only about 7 inches away, which is why i know there burnt. brown to a CRISP, burn makes on the leaves.

last pic is the one that does have hairs (the runt which is about 5 inches shorter than the rest)
the others are the burnt/no hairs. Best way i can describe it is

Looks like a bud, male, dense, HAD hairs, nothing now.

12/12 for almost 2 weeks now.

I had a crop that grew with pretty much no hairs, the calyxs just didnt open, still was crystally as all hell and some of the dopest dope i ever smoked.

your pictures are kind of blurry so i cant really see.. pinch off a tiny bit and dissect it, there should be pistils (hairs) inside of the calyx.

hope they come back good for ya :D
