Guys, thanks in advance for all your help.. I have never had this problem before and have just started running much larger plants.
What really does not make sense to me is that the same problem is showing across the board on all of our strains, yet two plants that are literally identical (Same mother, both cloned, nutes mixed in bulk so same nutes, same environment sitting right next to each other. One shows the problem and one doesn't.

You are running 3X1k of HPS?
I would like to add one additional question to your questionnaire if I may be so bold...
Do you foliar feed or spray anything on your plants?

I would move them apart now and add a small bit of H202 to the all plants in the course of figuring the problem out. You don't want this to spread. I know it may be tough but it's probably the safest thing to do until you know what happened.

No, it will only provide more oxygen to the roots. Don't add too much. I go with a shotglass into a gallon water can after they are pretty dry but you should calculate and research the amount before you go adding any.
How much bubbling do you have going on in those buckets?
Do you foliar feed or mist ever?

Hopefully someone with more hydroton/dwc experience will come in soon but is once a day all you water them? ..and when you say you haven't cleaned them this cycle, you mean, you haven't done 100% water change since you started them flowering?
1. Is each plant in a closed system or is everything hooked up to one rez?
2. Did you wash out the hydroton really good before you started?
3. I'm not familiar with the term Lolipop, can you please explain this for me?
4. Are your bucket black or can you see through them slightly?
5. I'm very familiar with FloraNova Bloom and the chart, can you give me the amount of FN that you are using per gallon? Can you also tell me the amount of each nute that you are using per gallon?
6. I would like to know the size of your air stones and the size of the pump / pumps in gallons per hour?
7. I would also like to know how many buckets you have and how many are linked up together?
Still reading......

lollipopping is cutting all the bottom growth to promote a bigger top cola it's done more in a S.O.G. style grow.
about your feeding are you going by the directions on the bottle? I noticed that you are adding back full strength, are you taking an EC reading before you add back? you might be adding additional salts into your water depending on how your plants are eating. try adding back fresh water un-fertilized plus your add back ph might be different than the ph already in your water causing it to sway until it levels out. your Tap water dose it have clorine or clorimine in it clorimine dose not evaporate over time like clorine dose , try using distilled or R/O water.

The more I am looking at your pics and your infirmary form I am thinking its more of an over dose of nutes . I bet you are over feeding w/ your add back. Are you mixing all of those different items in on all feedings? if so that might be it right there . I would run your plant in a florakleen for a day to try an leach out some of the salts accumulated, dump that water after 24 hrs. and add a lighter mix of nutes . Make sure to take an EC reading before and after your add backs. Ph w/ floranova is pretty stable or at least it was when I worked w/ it. With your add backs try just using plain water, after your add backs total the original amount of water started w/ dump it and start a new cycle. Try getting a PPM reading of your water before you start dumping everything else into it . You might just be exceeding your EC with your tap water.
All good sparkles! I'm sure I'll be getting a lot of comments like yours for the next few months. It's nice of you to take some time out, to help out a fellow grower!I thought you were an "expert with growing in all aspects".
Just razzing ya.

High nutes IMO, thats classic nute burn
High nutes IMO, thats classic nute burn. Heres your problems:
Top off each bucket every 2-3 days with full strength nutes.
How often are you giving nutrients? (If using soiless)
PPM- ?
In soiless watering twice a week, I would water half strength of whatever PPM I was trying to achieve.
EX: If I was trying to hit 600 PPM and was watering twice per week I would water with 300ppm strength solution.
Most people running soiless, but I do not speak for everyone, either water 1/3 strength each watering or water full strength weekly with straight waterings in between.
I use floranova bloom and I can tell you right now if your following labels your screwed. A FULL strength feeding with FNB and no additives is right around 8mL per gallon, which = 950ppm @ .5 conversion AKA Lucas Formula. You need a PPM meter because you are flying blind, back off the nutes and rethink your feeding schedule. I would run some fresh water over them a couple times to clean up excess and start over with a less aggressive feeding.
PS- I knew that was a Sour D burning up
