no offense to all of you guys, but I seem to have done exactly what this dude suggested (actually I started flushing with ph 7 water a few minutes before he posted ) and that dude has some more rep so I hope he is rightwell the runoff in the soil is a tad bit low first of all, which will lead to certain nutes such as mg to be locked out. no matter what amount of nutes you add, they will not be able to uptake because the ph is not balanced. i would get 7.0 water and flush the plants until the runoff at the bottom is 6.5-6.8.
when it does, feed with 1/2 nutes ph balanced to around 6.5 you can save them but the leaves will not recover, and since you are so close to harvest you will not see new growth to show you that the problem has been solved. just get your ph straight and finish them out.

ya know, it's not cool to diss folks that are trying (even though sometimes incorrectly) to help. i know it can get annoying to try and solve a problem, and hearing 10 different suggestions can be exasperating. that being said, i highly suggest you feed/water at normal ph levels, 6.5. YOU SHOULD NEVER CHASE PH!ya dude dont listen to these peeps
you dont have root rot, that is not the effect it has on the leaves.
the nutes you are using are fine, you are just getting lockout due to the low ph. and you are correct if you want to bring the ph up, you have to water with a tad higher ph so that it will bring it up and clear it out.. the soil will buffer the ph so its not like watering with 7.1 water will make your soil automatically go to 7.1... its a numbers game obviously it will be easier to bring your ph up to 6.5 by using 7.0 than by using 6.4. now that you have flushed em, water with properly balanced nutes at half strenght and let them chill.. you will be aight.FLo
ok nobody was attacking you so there was no need to defend yourself but anyways.ok i'm getting sucked in to defend myself and will go in to more detail.i have seen this in to many of my grows before i purchased seemorebuds dvds that garden gnome preaches, the spots on the leaves are probably ph,however there there is something else happening to, with the way the leaves are drooping and the tips are white(overwatering) and the leaves are a little on the lime green side if this was overfert the leaves would be a dark green and there are only 2 things that i have found that make the leaves droop overfert,and overwatering and without perlite in the bottom for the roots to have a safe place, leads to root rot and that is what causes the leave to die off like in the second and third pic usually from the bottom of the plant up
that, in itself is disrespecting other "peeps" suggestions. if you would have left that out....... except for the feed/water at a higher ph, i agree with everything you suggested. add a smidgen of humility to your posts, and you'll have info. to share that people will seek out.ya dude dont listen to these peeps
ok nobody was attacking you so there was no need to defend yourself but anyways.
white tips dont mean over watering,however it can be the first signs of nute burn.
lime green leaves are healthy leaves.. overferting does not cause dark leaves. only an excess of nitrogen causes dark leaves.
overfert in itself does not cause leaves to droop, overwatering, various lockouts, deficiencies, and variance in the leafs turgor pressure causes leaf droop
you also do not need pearlite in the bottom to prevent root rot, just maintain consistent waterings.. and if you do get rot in the upper portions of the roots you are screwed anyways.
and root rot does lots of different things to leaves depending on conditions.. you cannot look at that plant and say it has root rot without inspecting the roots.
