Nonsense... the answer here is to STOP ADDING NUTES!
Whenever you run into a problem, you have to simplify and then stand pat until you're sure the problem is corrected. This means light and water only. No nutes, no ST, no molasses, no worm tea, no bending, no nuthin'.
A nute-burned plant is in NO CONDITION to be taking in 1/2 strength nutes so soon after an overnute/pH problem and flush. You're trying to force her along, and she's telling you in no uncertain terms that it's not working. It takes at least 2-3 days after a flush for the plant to stop degrading from the old problem. Then, it will turn the corner and start adding new growth. After a week or TWO of that, you can make an informed judgement to whether more nutrients might be beneficial (this late in the game, I say NO).
Did you work any dolomite into your soil after your last flush? Once you blow out a soils' buffering capacity, it will tend to "go acid" a lot easier than the first time. Work 2 tablespoons per gallon (of soil) of dolomite into the top 1/2 inch of your soil. Watering will carry that down into the soil and stabilize the pH.
Here's the good news: YES.. your plant is very likely to make it the rest of the way. MJ is a tenacious bitch, and your plants have plenty of leafage left to carry them thru. I burned the fuck out of my plants, worse than yours, and they still made it. I flushed, cut off nutes totallly, worked in some dolomite, and just rode it out. Now, I'm sittin' on 11 zips dry of primo bud off of 4 females.
So, don't give up, but stop the nutes cold. Flush them again to get your latest round of overnutrition out of the system and then chill!! MJ is a weed, not an orchid or African violet; it doesn't need all that shit.
Good luck
