light burn on buds, made a mistake?

First time growing! I’m in week 4 of flower and have been worried because I’m growing in a very small space (2x2x4 tent). 2 of my colas were almost touching my 600 watt LED and this morning I panicked when I looked in my room to find the bud on the cola closest to the light crispy and burnt. I panicked and chopped it off but now I’m scared I made a big mistake. I should have just done LST by tying it down. will this ultimately effect my yield in a terrible way? (first pic is after the chop, second is the burnt bud after I already broke it open to make sure it wasn’t rotting, others are from last night)

I wouldn't stress, it's just one bud. Not sure if room permits but you might try LST to control the height of your plants

Of course it’s gonna effect your yield but experience isn’t free.

I would tie them down as you already said
