Crop circle auto (cream of the crop)

so the plant outgrew the light 4 times, but this time I didn’t catch it quick enough and when I woke up one morning the top leaves and hairs had been burnt, curled up and crispy. I removed them and it’s slightly recovered since but the top cola hasn’t grown since. The rest of the colas seem to doing fine which is good. Hopefully it can fully recover soon and I start to see some buds forming. The plant is over 5ft5 now maybe 5’6
