Heat burn during late flower

[Doos]

Hi all
I'm new to indoor grow and seem to have cooked a indica(master Yoda)
I have about three weeks left before harvest. I believe the lamp was too close to her and started to brown the leaves and dry them up, the sweet aroma has also ceased. Soil medium, and really healthy till this. Is there anything I can do to help her recover.....?
I have raised the light all the way up and now sits about 4.5 ft above plant.
Kelp supliment?
Or is it too late to help her, and just need to cut my losses and learn from my mistake.
Any insight would be greatly appreciated.
Cheers
Would kelp supliment help a cooked indica late into flowering?

typically, a leaf wont just turn brown from being too close, you would see other problems first.
Cupping leaves, gatoring, etc.

However, if you are overfeeding, and the lights are too close, the light will speed up the process of killing off the plant.

without pictures its hard to say, however, i would keep the lights far enough away that its not hot to the back of your hand, and flush the medium you use very well, then apply a very light feeding. 1/2 strength should be ok.
