Plant Yellowing/Leaves Burning

My plant is about a good 2 months old, and its well into the flowering stage, lately I started to notice that the plant was beginning to yellow, and some of the leaves were burning, im not sure what the problem is because I havent given it nutes in about 2 weeks, help please... also I have LED grow lights more then 6 inches away from the plants, i dont know what to do, help please

how bad is the necrosis? pics help

keep in mind most plants will decay a bit during flowering, its reaching the end of its life. the fan leaves will wither, micro nutrient deficiencies will appear.

If its well into flowering than it could not be such a bad thing, plants naturally leach the nutrients out of fan leaves during the ripening portion of flowering. As long as its not effecting your buds before your cut it could be aok,

yea ^ what he said. it really depends to what extent the necrosis is, and how the buds are looking.
pics. help. a lot.
