Any fan leaves that are mostly burned/yellow are not contributing to the health of the plant. The plant is putting forth (and wasting) quite a bit of energy trying to keep those leaves alive. Since your plant is budding, that energy should be going to creating new flowers, not keeping the damaged fan leaves alive. Remove any fan leaves that are at least 1/2 yellow. More will turn yellow in the next few days. Remove them also, when they get 1/2 yellow. Since your plant is budding anyway, it's trying to 'reproduce' by creating flowers. It's not trying to grow bigger. You may experience a later harvest, but removing the damaged fan leaves is the best thing you can do for your plant now.

HTH.
