Purple and yellowing seedlings

Hey guys first grow going not exactly as planned they started off great but around day 6 from sprout started to see stems turning purple and first set of leaves began to turn purple as well
Fast forward 2 days and they all appear to be yellowing as well
Growing in Scott's top soil
30% perlite
20% sphagnum peat moss
50% scotts
I water when I feel the top 2-3" of soil is dry
They are under 6 15w led bulbs running 24hours
Temperature ranges from 75 at night to 85 during the day
Any help would be greatly appreciated

to acidic

Thank you I will try raising it but wont be able to test ph for a couple days while I wait for the mail

imo just grow coco and perlite and you'll have a better time, when I hydrate coco bricks I just use a gallon and half per canna coco block
the water I used has a ph of 6.4 with 6 grams mega, 1 gram algae extract and probably a quarter of a gram of megazyme and to ph I use nectar for the gods Olympus up and hades down works fine for me.

Give them some time. I would not add anything to them, they don't need anything until they get about 6 to 10 inches tall.

So far only added a small amount of lime I'll give them as much time as they need hoping for the best

I would just let them chill, pH probably isn’t your issue, not with your mix. They are just building roots to uptake nutrients and might have minor initial deficiencies. No worries!
