1st off chill bro the clones look fine & damm near the same as my rapid rooter clones , i fill all 50 sites once a week & have done so for 4 yrs straight .
Thrive Alive & Super Thrive are useless & the last thing you want to introduce into a high humidity enviroment , heat plus light plus nutrients = mold & alge .
Cloning in a humidome you cant expect to see roots popping out everywhere in 5 or 6 days , my humidome rapid rooter clones normally take 2 weeks until 99% of the clones in the tray bust bunches of roots , humidomes are much slower than air cloning or hydro cloning .
Here is what i do , take all the unused sponge plugs out of the tray & leave them out , next take each clone & make sure it dont spin in circles or is loose within the plug , a loose clone wont root , flipping the plugs upside down where the fat part is at the bottom helps keep cuttings tight within the plug then you insert about half the plug into the tray , it keeps the cutting nice & tight that way .
Next take each cutting & dip the sponge plug in room temp water daily & let it sit in the water 4 or 5 seconds , tip the plug over where the cutting is tword the floor then gently squeeze roughly 90% of the water from the plug , this helps force water into the stalk & helps prevent embolisms , the plug should be damp all the way thru after squeezing the water out , not soaking wet , once you see even a tiny root stop squeezing the water from the plugs & keep them moist not soaked or dry .
Unless your room is under 70 degrees shut that heat mat off , after all plugs have been soaked & squeezed spray them lightly with plain water once or twice a day while keeping the air vents closed , mist the inside of the clear humidome so the clones are in 100% humidity , you want the dome to have water droplets all over the inside of it at all times until you bust roots .
You should also trim away some of the leaf material , i normally trim off about 25% of each leaf , this helps keep leaf rott down , leaves that are crowded will rott & create slime on leaves .
Dont expect 100% success either , no matter how skilled a grower is at cloning he's gonna loose one or two .
