Steez-
To answer your question in short, you don't want to risk it.

I strongly suggest you make every effort to get those plants further away from the light. If you can't move the lights, move the plants by tying them down. The problem will only get worse and will most definitely result in having dead/dying plant matter if ignored. Dead plant material on your crop could potentially attract mold and other pathogens, which could destroy your entire crop!

It's hard to tell by the pictures how much room you have, but as a simple solution, I would clip some fan leaves below the burned/burning colas and replace the colas in their place by tying them down. You could try clipping off the burning colas too as a last resort; this would avoid having dead plant matter, but will obviously substantially affect your yield.

Good luck!
