shot in the dark but looking at all that black I bet its root rot from having too warm growing medium. The foam the pellets and or the Rockwool is too hot, not the water temp.

That's some type of root issue!
The white "one" at the bottom is the newest so the least effected.
Dump everything and place your plant in another by bucket. Sterilize your equipment with a string dosage of either bleach or even better hth pool shock. Rub it down the best you can and then rinse it out and finally rinse and repeat with plain water.
Refill the system with 1/4 strength nutes and 1/2g of hth pool shock per 10 gallons. Then add that amount of pool shock every 3 days. It may work or it may not but those roots are tore up from the floor up. Theyre not just dyed but fried from the looks of it or they would have considerably more lateral roots.
When your plant is sitting out wash the roots down in the sink or shower and allowing any to fall off that do. You could even dunk the entirety of the roots in a bath of h202.
If you decide to do any of these things i can point you to specific numbers and ratios.

she is fucked. try like above post said less nutes add some cal mag move light up change ph to 6 also calibrate ph meter change your res once a week don't let water temps go any hotter then 23c use a 2 part nutrient not any organic crap. keep water air-rated 24/7. probably better to just start over and sterilize everything correctly before starting. if you keep it clean and keep your temps in range you shouldn't need h202 just my 2 cents

Roots get sick die and then new roots grow out of those and a couple days later they die. I lost my last two crops to this issue and mine was much less effected than yours are.
I agree that it's probably better at this point to start over butbi hate quitting, it cost me lots of time and money for a lost crop in the long run.
I'm all about running sterile due to some issue with my water source or grow enviroment. If you run sterile at a high enough ppm of chlorine you wont have another issue.

just have to add this. if your growing hydro and your calming your ph it staying stable at any range and not fluctuating then you are growing wrong and your plant isn't drinking or eating as the ph will change depending on what the plant is doing.
you need a fluctuating ph for example start at 5.8 allow ph to drift to 6.3 ish before re adjusting it down by doing this you are allowing your plant to uptake different nutrients that are available at different ranges of your ph. yes you can keep ph at one point using a auto doser but it will make it easier to get deficiencies doing that

i have wasted $2000 learning to grow and i have a long way to go still and allot more money to waste
Please always follow your instincts. We're online all we can do is give crap guesses. You're there n know what you been doing or not doing better then any of us. I agree with you it's prob cal. Now if that's bc of a lack of, abundance of something or ph? Here's the best record I've found online for plant problems https://www.icmag.com/ic/showthread.php?t=11688

Well can Cal def. cause nutrient lockout? Cause if so that would make perfect sense. I topped off with RO water and added some more nutes to increase ppm but forgot to add Cal/Mag that's when I started to have problems. PH stopped rising completely.

them roots cant drink they are pretty much fucked. ive only had root rot once and it wasn't that bad i have tried using h202 and have even tried using a few drops of bleach to stop the rot but never has good results doing so. only was i could find to save the plant was to put it in soil and the roots did recover but took a month yet the plant was too stresses at that point and went male. you could try flush clean everything and pray that the roots start growing again. while you are doing that start a new seed just incase the current plant will not recover. the top growth of that plant is still green so not all hope is lost

address the real problem the problem is bad roots. roots cant uptake shit in that condition but go ahead leave them like that and add more cal it wont make a difference
I
I didn't say to add cal did I?

I've never seen a clearer example of root rot and seen ones much better off tossed out. He does have a deficiency and it's caused by his roots being dead.
Like I said you already got the answer bud. Using ro and cal deficiency go hand n hand.
He'd be able to physically see root rot
