These are being grown in soil under a 430 watt HPS. I had some outdoor this year that had was attacked from blight, and it kind of resembles that. Any ideas or suggestions?
mtbazz,
What water are you using? How about nutrients?
Did you check the ph of the soil before using and what soil was it.
There are so many things that can cause any particular problem including deficiencies of one nutrient caused by an excess of another. It's just easier to try and figure out what's causing a problem when you have more info...

The water I am using is well water from my house. These are three weeks into flower, and they just had their first feeding during flowering two weeks ago with some pure blend pro gro and bloom (tbs per gallon bloom, 1/2 tbs /per gallon gro, and 1 tsp per gallon catalyst).
I just flushed these out with fresh water, so hopefully that helps.
These are some hindu kush that came from some freebies I got years ago from johnny reeferseed, the funny thing is, Ive got three "fruit of the gods" going also, and they have gotten the same types of treatments and are doing fine.
Funny that Bterzz said that he had a plant do that from RO water because I had some Afghan do that using tap water that was 350ppm and the problem resolved once I got a RO unit. Most nutrients have plenty of Ca++ and so when you add to that with really hard water...then you can get such an excess of Ca++ that it can lock out other nutrients.
Do you have any idea how hard your well wate is? Water from wells can be super high in Calcium. Have a meter? How do your ice cubes look? Cloudy?
Different strains have different nutrient requirements so it doesn't surprise me that not all your plants are effected. Are they all in the same soil?

I dont have a meter, but it must be pretty high. I get alot of calcium deposits in my tea kettle, andmy ice cubes are milky and when thawed in water leave mineral deposits. I cant afford an RO unit yet. Would a brita filter work?
If you could buy some RO (usually sold as "drinking" water) or distilled water...and mix that with your tap water 50/50 to dilute it, that would be better then a Brita and certainly better then nothing.
Or if you have some water jugs maybe you could fill them at a gas station in town. Maybe tap water there is lower tds.

So, since my last post Ive been watering this one with distilled water only, and have fed once with a very mild feeding solution, and things are only getting worse. Id say that a good 2/3's or more of the plant is now suffering, and with another 4 weeks of flowering to go she may not make it.
I figure I have three options:
1) Transplanting and letting finish. Will transplanting it into fresh soil at this stage do any good?
2) letting it finish in the soil it is currently in. with this I run the risk of not getting anything.
3) Chopping now. Be the earliest Ive ever harvested, but at least Id have something for my efforts.
mtbazz,
Agreed, you have limited options. But assuming that there's something amiss in your rootzone...a good flush is always a good idea. I don't normally flush nor do I advise to except when all else is failing.
Flush with around 3x the volume of the pot. Allow to dry a bit and slowly resume nutrients. It isn't a perfect solution, but it gives you something possibly helpful to do right now.
