glad to try
I am assuming you are cutting at a growth node and all of that??
your pump is a bit bigger than mine,Im sure it just blasts water.those things need to be pulled apart and cleaned after every cutting run,pvc,hoses,pump filter everything sterile.even the net pots and pucks
are you using R.O or tap?? powder or jell rooting compound?
believe it or not,tap water seems to work well,and if you look at this chart,(my city water)it shows why.Its full of bloom nutrient

If you find that the pump is warming the water to much,then try a timer set it to shut off 15 minutes every hour,ive had to do this myself
I would clean it all up,make new cutts and put 2 gallons of tapwater(more water keeps pump cool) add some aquasheld and some bloom nutrients,maybe 3ml gal turn it on and watch it go
if ya need to use ro,then add 5ml gal bloom, aquashield never a need to set ph in the cloner,the roots are not eating,they are just growing
brown,slimy or gym socks is not a good sign and indicates rot,I know the smells.
low level light and some humidity.
