New grow, 5 in a 4x2, seedling starting to yellow slightly

Just started a new grow, 5 autos in a 4x2, I know this may be a squeeze if they do ok, but wanted to try anyway as I got a freebie auto. Strains are gorilla cookies auto (this is the one starting to yellow) wedding glue auto, apple betty auto, gorilla glue #4 auto (this was a freebie) and skywalker haze auto, all from herbies. I'm attempting as good a go at living soil as I can in 5 gallon fabric pots, the mix I just kinda winged, I should have just tried the one in this mix I reckon, but a lot of searches seemed to imply that it shouldn't burn them as seedlings. I started by going to the local woods and collecting a big bag of spongy, crumbly black leaf mould from under a few really old trees and some of the wood material from the underside of old rotting logs, the type that's turned into a sludgy consistency, and mixed the two together, removing any insects as I went, there seems to be no fungus gnats present. I mixed that up and used it as a one part mix to 3 others, tomato grow bag soil from westland, perlite and coco. Amendments, I used a very light mix of living soil's grow and bloom, some of their mycorrhizae and watered lightly with spring water with a turkey baster a few days ago. Lights are 2 mars hydro, I got them from a mate's mate, two ts1000s I think, one looks to be a newer version? never used them before but heard they're not bad. Temp is around 25 degrees humidity 75 ish, AC infinity cloudline extractor and filter from last run, but it's not on yet, no real heat build up with these drivers off, I just leave the top of the zip flap open until the smells begin and they're on 24 hours anyway.
I know it's only slight speckling and margins of yellow, but could this be a sign that my mix is a bit wrong? PPFD I checked with ppfd meter app, lights about a metre away, 30% power and it's reading within recommend specs for seedlings, slurry test of the soil comes out at pretty much the same as the water, 6.5 ish and the ppm although probably useless reading from it comes out at 400. Any thoughts/ideas welcome, cheers

If you started in this mix and this is the current growth, you made it! I'd keep doing whatever it is your doing.

I see you have two fixtures, you only need one for veg/seedling stage. Save some money.

I may just remove one and put the bigger one in the middle, I just thought more coverage would be a bit better that way.

Is this type of mix something you're familiar with?
