They will probably be ok but something caused it and you need to isolate it. What all did you change? How much did you up nutes? Are you checking pH? etc etc

What's your pH? What nutes are you using and at what concentrations? Details people, we need details to help. :-)

You're nutes are too strong. Drain out some water and then add back plain ph balanced water. They'll show within a day or two if this helped. Try to shoot for 800-1000ppm

When switching over to flowering, gradually increase your bloom nutes.

Oh yea, try to get your ph around 5.8 to 6.0

Sure, they'll be fine. Pot is really tough to kill.

After flushing out the nutes, start adding back some nutes slowly until you get to 800 to 1000ppm. Take a few days to add back the nutes.

If you flushed them today, they should be looking better by tomorrow or Thursday.

Watch how fast they snap back.

By the way, always dilute your nutes prior to adding them to your rez.

ie mix them in a bucket with a gallon of water and then add to your rez.

The reason your plants died in flower is because of Mg lock.
During the bloom phase the plant demands a lot of Mg
You are using tapwater, and that is the problem
RO is the solution
Get an RO machine for under $100 at purewaterclub.com
Then use lower nute loads as suggested above.

You may have root rot.
With your rez temp above 70 the odds are not in your favor.

Light green plants could be a indication of too high pH

Picture would really help

Wow, I'm surprised that they didn't respond better to the flush. After seeing your pics, I pm'd Uncle Ben and asked him to stop by to help you out.

Also you may want to post a detailed thread over on the MJ Plant Problem section:
https://www.rollitup.org/marijuana-plant-problems/

Usually a good flush will clear up any over nute problems.

Sorry I can't be of more help.

Shorty, you really need to address this member's question. What did YOU change? Plants just don't croak by flipping the switch to 12/12.

Looks like moisture stress caused by......

Good luck,
