6 foot White Widow top bud burn from lamp

Hi people!:rasta:
My 6 foot White Widow got too close to the 1000 watt light a couple of nights ago and the leaves on the top bud started burning up and the very top of the bud had kind of dried up because of the heat from the lamp,,maybe the top 3 inches dried up,The top bud was about 14 inches from the lamp,,,,the rest of the plant is doing extremely well,,the buds are crystalizing like they should and have maybe another 2 1/2 weeks of flowering left before it's cut down,,,,my question is about the top bud,,,it feels dry to the touch and I don't see much crystals forming on the very top part, but like I mentioned, it's only the top 2 -3 inches of the main bud,,will it harm the plant?,,will the bud be smokable ?What are the chances the bud may come back to life and start producing thc again? Thanks for your thoughts on this,,,Bass3rd:smokin:
