Need advise, huge problem with burning

Hi guys,
my m8 here has a chronic problem with burning on the leaves, he has been flushing 5-6 weeks and still got a problem with burning on the leaves, the plants are about 4 months old! the plants have been giving no nutrians in the last 5-6 weeks since i last posted up, the problem hasnt got much better, he is using miracle grow soil, there isnt much heat while you put your hand over the plants
any suggestions are welcome

N-P-K defency...its an easy one...your crappy ass MG soil is depleted of nutrients also flushing them has taken any nuts. left out of the soil. trim off any leafs that are over 50% yellowed if they have yellow tips trim those off too. also i cant see the pots they are growing in but i suspect they may be root bound causing slow and slugish growth. im almost sure of that due to their size. rootbound is when your plants have overgrown their pots. how big are the pots? how old are the plants? you need to start fertalizing agien! after you trim them, do the trimming just before the lights kick on to reduce stress. i would mix you nuts. at 25% or half strenth and feed lightly every other day for a couple of weeks. dont over water make sure the soil is dry before you add more food. the best way to do that if to stick your lil finger in the soil. your plants will hopfuly recover after a week or two..id think of flowering soon too some plants double in size in flowering.. they grow at least another 12 to 18 inches in flower..so... if im correct about the rootbind you may want to transplant after your girls get healthy. youd need 10 gal pots to support those monsters damn hope your ladys pull threw itll be a monster harvest for the record books.

Thanks for your reply just wondering if humidity could be a factor as the room he's growing in is very warm in your opinion does it look heat stressed..?

Doubt humidity, like swager said. He nailed it.
