You are doing what most new growers do.
You are loving them to death.

Cannabis is a weed.
And those li'l weeds are just barely seedlings

1st.
Lose the Superjive.
It is horse exhaust.
Been tested many times by real botanists and found to be, basically, worthless.
Won't help, and can hurt.

Also, stop with the additives, and give them less light.
If they start to stretch, they want more light, but generally, they expect low light early on.

At this tender age all they need/use is PHed water.
They can not use the rest of that crap.
That's what the cotyledons are for.

So, raise the light to 36" (Mo' betta switch to CFL until they start to grow)
Then, plain water while they feed from their cotyledons to grow roots.

When the cotyledons start to yellow and shrivel, start with a very low concentration of vegging ferts
1/8th or less at first of veg. ferts.
And you might want to raise the PH a little.
You will know that by watching the stems.
If the stems start to turn red, raise the PH to ~5.8 and continue to monitor.

While you wait for them to recover, click on the first link in my sig. and read 'til your eyes bleed..
The information is all there and it free.
