lol... 10k... That's a shoebox grow by BC standards... (I keed, I keed!)
Your primary concern is going to be dealing wiht the low pH and flushing out the excess fert salts.

You are a big ass grower I take it. So flushing pots individually is not exactly your #1 most favorite way to spend the whole weekend... try this on for size:

Mix up your res with JUST your base bloom fert and calmag, mixed up weaker than you would normally. Put aside the bloom blasters for this feeding and the next. Now set the pH HIGHER than you like it to be for your soilless mix, but not outrageously high. Personally I would choose 6.8-7.0 as a good number to offset runoff 6.2 and with any luck land you right back in your preferred range.
Now I also assume that since you are a big ass grower, you have floor protection down, or drains.
WATER THE LIVING FUCK outta those pots. You are not doing a complete flush, but you want some serious runoff to wash away excess salts. Do this heavy watering once or twice, then go back to your normal fert routine, but this time, monitor your runoff pH (I'll give you a hint on that in a sec) and make sure that if your RUNOFF is low, you run your RES just a touch high to offset that.

Okay. For the runoff thing. Testing a zillion pots individually is going to be a PITA so I'd go around with a big bucket that you have scrubbed and rinsed well with plain water, and a watering can of plain water, preferably RO, but as long as you know the pH it isn't all that important. Just go around the room and randomly pick a handful of pots, pour water through just to runoff, catch this in your CLEAN bucket, for a 'pooled' or composite sample, and test the pH, whcih will give you a general idea of how the population as a whole is doing.
Anyway good luck with your harvest... repeat after me:
PEAT BASED MIXES SUCK AFTER 6 WEEKS!!!
PEAT BASED MIXES SUCK AFTER 6 WEEKS!!!

lol! Repot early and often!

So Stinky......I see you are a fan of peat based mixes...... (I keed I keed!)

Shhhh don't tell anyone, but guess how I learned about their properties? :wtf:
You ever take a good look at the media in that continuous canopy thread?
You know how many bales of fucking promix I go through? EEERGH. My back protests every time I drive by Agway.

Edit: (I keed you not! hahahaha)

I hope this works, it looks as if could be the answer. You know I just started having these problems in the past year. 3 in a row have gone bad. Prior to that I put out some beauties. I have upset some people, that is why this is just not making any sense. I have gone to Pro-Mix from SUnshine, but I am still stumped.

I want to thank all of you for your help, it has been amazing the response I recieved. I wish I could repay you for you assistance.

My local has a product called CAL-MAX, sounds like the same sheee-it. Let me know if its not, but I will check it out.

FOLLOW UP QUESTION

Would you suggest using a product such as Final Flush in conjuction with your nutes such as CAL MAG if you are trying to mend a problem such as the ones I have shown in this thread???

All through Veg and the first 3 weeks of flowering the ladies where nearly perfect. We were very impresssed. Are you suggesting that peat based mixes just go bad after a certain amount of time?? I know I was not pushing the ppm. ALthough I used a couple of supplements with my reg program, I checked everything out with my local shop and they said it was cool to work this way and they gave me a schedule that has even more products being used. I am just trying to avoid this happening to me again.

Would adding lime to each pot help at this point?? I know it would not be real even,,,,,,,,,
