if you look mg perlight has time release nutes you've got nute burn ,its always better to start out at 1/4 strength to see how the plants will react to the feedings

I second this. Flush with pH adjusted water for a couple of waterings and it will clear up. Like Robert said; Start back with 1/4 strength nutes.

Another small tip. I use the same cheapo thermometer you use. Disassemble that sucker and drill some holes in the plastic housing. This will improve the accuracy of it. The only vent those things have is a tiny hole behind the clip/stand. I did 2 side by side and got up to a 5 degree variable and 8% on RH.

Why can't the one be nute burn? Once it is effected by nute burn it can show in many other ways. If a plant suffers from too much nutrients it effectively shuts down intake and this can show as other deficiencies. Up curl tends not to be a sign of nute burn as much as under curl is. I would lean toward pH for that. Are you checking your runoff?

Have you checked your runoff ph? What looks like a deficiency can often be caused by nute lockout.

also for next time. what soil should i use at first in order not to burn them. and how big or old should i let them get before i put them in my perlite and peatmoss mix. i'm trying to get this down because these are just blueberry bag seeds. but i baught a seed online for $10 just for one seed so i dont want to mess that one up so i can use for mom for clones

Nitrogen Toxicity:
Leaves are often dark green and in the early stages abundant with foliage. If excess is severe, leaves will dry and begin to fall off. Root system will remain under developed or deteriorate after time. Fruit and flower set will be inhibited or deformed.
With breakdown of vascular tissue restricting water uptake. Stress resistance is drastically diminished.

the mix and timing were fine just check the labels for nutes no nutes for the first few weeks
