That looks like nitrogen burn to me -- starts on the lowest leaves, while the ones above are super-dark green and droopy. If you're using pre-fertilized potting soil, try cutting back your watering. If not, stop adding nutrients and just use plain water until your top set of leaves gets a little bit of a lime-green cast to it (then, start back with nutrients at quarter-strength of what you were using). If your soil is NOT pre-fertilized, you may be able to advance the recovery by flushing -- that is, watering with about 2-3 pot volumes of water so that the water flows out of the bottom of the pot, taking some of the excess nutrients with it.

The damaged leaves won't come back to health. Go ahead and cut these burnt-up things off. Be patient; don't try to do too much or go changing everything. The problem is probably simple, and MJ is extremely resilient. She'll probably come out just fine even if you didn't change anything.

Pics are always great for diagnosing plant problems. Even so, folks could probably help you more if you posted a rundown on your light power, soil type, nutrient regime, etc.

thats burn bro. cut your nutrients by a quarter. so if you are using an oz. per gallon, go to 3/4 oz. and try 3 or 4 drops of superthrive every watering to stabalize ant stress and it helps out throughout anyways. try it out, its cheap and it works wonders

Do you have holes drilled into the bottom of that bucket? If so, is it on top of something so that water can drain out if needed? What kind of water are you using, tap probably? If so whats the PPM of your tap alone? What is the PH of the water you're using? Also what is the PH of water that drains from the bottom of pot? How often are you watering and fertilizing?

From what you've told me I would cut off all Yellowing portions of plant. Then flush with Clearex, but its hard to tell without knowing all info...
