Iv had 100% rioting doing it just like that for the last 8 batches Iv done this is the first timeProbably the clonex solution, I believe that is for established rooted clones or seedlings, not for rooting clones. From what I read it is nutrients for baby plants designed to work in conjunction with rooting gel. I would leave out all the stuff and put just pH'd tap water in there and wait. I've had great success with just tap water, it's got chlorine in it so you don't need the clear rez. Leave the nutes out until transplant. Just my two cents.
Oh yes that might be it I did use bleach to sanitize it but may of not rinsed it well enoughWhat was the last thing you used to clean the system?
Bleach residue will foam like that
Was that your problem?Oh yes that might be it I did use bleach to sanitize it but may of not rinsed it well enough
