honestly i think rusty T is right about the lights. you said you were getting roots developing at first with the lights high up untill you started lowering it. when you lowered it, the clones focus prolly turned around and started on the leaves rather than the roots causing them to root out like that. plus i think all that crap your adding to the water isnt helping at all!!. i dont think its lack of oxegen in the water cause the spray heads imo do the work, most people that make these diy cloners dont even use em with great results. this is mine after 9 days. i just use plain ph ro water at 6.3 with temps around 72-75. the light above is "1" t5 light (i unhooked 3 bulbs from my 4 bulb t5 setup) at about 13 inches from the top. since you cant unhook any of your led diodes raise it up really high. as of your slime, i have no idea how to fix it cause i never came across that type of situation. i heard hydroperoxide helps but dont know if that will cure your prob. good luck next time. just remember do like rusty said "make a fresh cut on your clone for air bubbles" and raise that light. i also would just use plain water with root hormone on the root so it dont get airbubbles while putting it in the cloner. good luck next time bro!

hey how come you got 2 cann.com accounts? or is it someone else saying they got slimed?
