some don't look like they have any roots. they will do better once you plant them in soil or something, water then let them dry out for a while. cutting the dead growth off would help but you should have 5 to ten good ones at least.
Check the temps of the water--
Our EZ cloner worked great a couple of go-arounds-- then the pump started heating the water...
Also- what is in the rez- and how often do you change the solution???
They are starvin-marvin... Cloning solution helps prevent that... so does a little liquid Karma and superthrive... both at 1/4 rate...
You MAY be able to save them IF you change the rez and feed them.. let them go another week and see what happens... but make sure the rez isn't heating-up. If it is- you will need to put the pump on a timer- 30 min on 15 off around the clock so it doesn't have a chance to overheat....
Ok cool! So the water stays very consistent between 74-78 degrees. I used spring water, ph 6.5 and ez rez solution. The moment I saw roots I added hygrozyme and that's been it....I have both super thrive and liquid karma....I need to empty the water or can I just add the 1/4th nutrient solution? !
