Seedling burn from Ocean Forest?

I have 11 two-day old seedling of various strains, all under the same conditions.
Small peat pots each filled with FOX FARMS Ocean Forest soil, and 3 26-w CFL's (till they are big enough for the 400w HID)
I water about twice a day.

It seems my Blue Mystic strains are already getting signs of nute burn, brown tips, yellowing, and slower growth
However, the rest of them all look perfectly healthy.

Could this strain just be less resilient to the strong soil, or could it just be a poor strain?

(Photo 1 is a comparison between the normal healthy seedling and the yellowing blue mystic)
(Photo 2 is the brown nute burn on one of the blue mystics)
(Photo 3 is a group picture)

I don't soak, I just get mist the soil because it dries out so fast.
It's only about 80 F in there, 85 at the most...
Like I said, I'm only using CFL's, so I don't see what soil temp has to do with nute burn.

"hot" soil means it has fertilizer in it. don't mist twice a day. water when dry.

He means "hot soil" as in soil with nutes already in it..Next time start your seedling off in a bag of Light Warrior soil.

Aw, I see, this is my first grow in 3 years so I'm not up-to-date on 'hot' terms.
You think they'll green up again after a developed root system happens?

Too hot for seedlings I doubt if they grow any they'll just sit there and sizzle like bacon.
I use ffof but start'em in sunshine mix 4 for the first two weeks you have to feed'em a
little the second week but then on the start of the 3rd week you transplant to ffof here's
a pic this is just before I transplnated them into ffof ~ YOu wanna have at least 2 sets of
real leaves!
I would save the dirt don't water it any more and start some more seeds asap in light warrior or sunshine mix 4 use flo's the first week then MH light the second week is how I try to do it.....
