Help my plants are dying

Hello i just made this account I think my plants are dying. I´m from Chile so please excuse my english.
1 Month ago i made this low pressure aeroponic (a dwc sort) system (4 buckets each with a plant around the main res)
Everything was running super cool til 4 days ago. All i did was change the old water (after 14 days) with new water and the same exact nutrients.

The Ph, Ec and temps are being controlled every 8 hours or so..

This was yesterday: (looks good but the plants are starting to look very depressed)


so i check the roots and NOTICE A BIT OF ROOT ROT IN SOME OF THE ROOTS, so i add a bit of bleach to the res ( 8ml to the 11 Gallons )



This is the plants today:




Please any help is welcome. Thanks

This is my first hydroponic system (on soil for 15 years)
The PH is always between 5.5 and 6.0 the EC is around 0.9 and temps are 68-71F and 4 air stones 1 for each bucket.
The PH in the last 12 hours is stuck at 5.8 (meaning the plants are not eating?)

I would do water change with nutes and add southern ag or hydroguard , this should take care of rot , but make sure to flush all bleach before adding sag. Do u give any root enhancer ?

Thanks, yes i put the the hesi hydro pack in the res but nothing else...
- hesi root complex
- hesi powerzyme
- hesi hydro grow
- super vit

i would try to find some similar product because there isn´t any of them here in my country i think..

I use gh rapid start and see huge result.

I change the water and add a bit less nutrients today.
