I use LED too. It is quite easy to bleach them as the LEDs run cool. Its easy to think you can keep the LED close as the plants wont burn.

The plant will continue to produce bud but I wouldn't smoke the bleached part. It is damaged and wont become green again in that area. But the bud will continue to grow.

Certainly move the light higher or maybe start some low stress training on the plants. This will allow the LED to shine on more of the plant. You will have more tops too which usually means more yield.

Good luck
