My roots vanished wtf????

I have cuttings in a clone machine, the other day the roots were starting to form and now they have vanished. Has this happened to anyone else, and should I start all over.

you seeing things or they got burnt right off ? nutes in the water ? i use only plain water even if takes a week or 2 to show roots then feed at 500ppm - look at the bottle it will show you a feed for "rooted clones" only not fresh cuttings - by the way i had zero luck useing rooting gel and opted for moms tried and true method for cloneing house plants - worked for her for over 30 years .

clean your tub and get fresh water you might have gotten root rot allready i used iguana juice in a bubblier bucket and it set me back 2 weeks
