Too close to the light and burnt

same problem to me try super cropping on it

Too late for topping, but not too late (just) for training. Or you could try some "knuckling/super cropping" - just bend the branches slowly until they snap and leave them to recover. This way they will come down well below your light. Just google "knuckling cannabis" and there will be a wealth of information.

bend it...

Bend it over

Wow brother. That's a pickle. I'm not a genius grower at all. But I'd say, you no choice but to do one of two things. If you can, LST them now with string. Bend them over if you can and see what happens with the burnt one, you may have to say goodbye to the one by cutting it. But to prevent any more burning, break out that string.
