Well its hard to say.....if the problem was caused by too much nutes than it's iffy....once burned the plant is burned and it looks like most of plant is involved there.

If the problem is your ph being off the plant will probably be ok but you may lose some leaves. It depends on how far off the ph was and for how long. That's information you may never know so it's most likely a wait and see thing.

The thing is.....both problems go hand in hand....too many nutes will cause your ph to rise and do strange things so then you have too many nutes AND your ph is abnormal etc etc...see what I mean? That's why it's good to attack the problem from both angles.....less nutes (which you've done) and good ph (which you are working on) That's all you can do.

Just out of curiosity....why only one plant? Looks like you have room for several in your setup.
