Blue cheese seedling

[Stilton]

hi guys, ive had a look at some of the guides, but i cant put my finger on it, its still quite early, the leaves looked fine last night, then this afternoon, the edges were ever so lighter, their only babys, just over a week old! her leaves have been pointing up alot aswell
some info on location/equipment;
100ws of cfls, 2x 20w 2700k and 2x 30w 6500k bulbs, the lights are about an inch away from the plants, and ive got a small pc fan blowing directly at the plants, but they dont even sway, just for air movement..
i water with bottled water with a PH of 6.2, i normaly give about 100ml every morning
for soil ive got west+ multi purpose soil, concerd it would be a little hot i add bit more perlite than usual, roughly half and half but leaning slightly towards the soil side,
i havent given any nutes yet, just half stength Bio silicone and Catalyst from Plant Magic, and ive waterd in between! so i dont think its over fed, or the soil was to hot, the problems wouldve been instant?
Temps are fairly varied, about 60-65 lights off and 75-85 lights on.

i think it may be down to over watering, i checked em both last night, the white russian was almost completely dry and the blue cheese was still moist, so i gave both a little watering with the half strength Bio silicone and Catalyst to get them through to the morning when i normaly water..

Blue cheese

nice healthy Auto white russian!

any ideas guys? thanks!

well the actual leaves havent got any worse i dont think, but the seedling leaves are more yellow, i know they die off early anyway, but the white russians fine! still nice and green!

i dont wanna give any nutes or flush until im fairly certain i know what it is!
i always water until i have a little run off, could i have unintentionally flushed her?

thanks again guys

Yup, overwatering. In addition to that, pots waay too big, no O2 at the roots. I've noticed that the smaller a container you start seedlings in the faster they grow. Even a half filled nine ounce solo cup is not quite as good as those 'pony' sixpacs you get tomato seedlings in. Also, little seedlings don't need any nutrients in their starting mix, but if the container is very small, they can actually tolerate some nutrients and will grow fast rather than show signs of over nute, like they will in a big container of the same mix, but where there's no O2 available to the roots. Best thing would be dig 'em up and repot into half filled 9oz solo cups with big time holes in the bottom.
