Plant Crisis, Dying after switching to 12/12 and flowering nutes

Im a total newbie on my first grow. Indoor homemade bubbleponics kit growing 8 plants from clones. I'm using the fox farm line of nutrients and just switched to tiger bloom, aka week 5 on their feeding schedule. After the first 12 hr dark period with new nutes, one plant began to wither rapidly. It is looking really bad and now the other 7 plants are starting to look droopy also. WHAT the heck happened??. Any help is greatly appreciated

sounds like the nutrients, how much did you use and what is your ph?

Followed the feeding schedule. 2tsp/gal of tiger bloom, 1tab/gal of big bloom. pH level is 6

Maybe a touch to much on the nutes you should always start at 1/4 to 1/2 stength and build from there. And maybe drop your PH to like 5.3 to 5.8 for hydro growing. 6.0 or higher is more for soil growing.

Heres a pic of my wounded baby.

looks like it needs water what kind of system are you running how often you watering?

It's a continuous drip system. i have 2 air stones in the reservoir pumping oxygen into the solution. im thinkin the transition to new nutrients was too abrupt?

you might have to high of a temp in the grow room looks like heat stress

Looks like it's getting way too much water. What's your root system like?
