Stunted Health & Growth of Seedlings

Hey everybody. My friends first grow with a 400w mh. They were born 4 weeks ago! They are showing some health issues, and don't know if they are water, nutrient, or other causes.
Here are the facts and pics:
-started in peat pellets, then transferred to bigger pots 2 weeks ago
-soil mix of 1/3 perlite,1/3 spaghnum peat moss, 1/3 organic pot soil, 1 cup of some dolomite lime per 3g
-watering every four days
-not fertilized yet, however we flushed two days ago fearing nutrient burn from fertile soil, or hot spots from the lime
-a few dark spots, browning and yellow bottom leaves..possibly from spraying too much with water?
-used sulphur spray fearing fungus (black spot, or powdery mildew)
-soil ph of 6ish, water around 7(mountain soft water)
-Light is now 2 feet away, brought down from 3ft one week ago
-temp is 78-84, humidity 48%
-2 plants look super strong and healthy but have lower leaves yellowing a bit (nitrogen deficiency already?)

Please help and give first aid advice so we can get our girls back on track! Thanks!

i can totally relate to this thread, my first gro last yr i got nute burn on my seedlings, i had to flush, this caused the soil to be lighter nutrient-wise giving me deficiencies, watering every 4 days? does she need the water or is it a schedule? at this stage she wont drink as much, i have a decent green thumb when i first started and i knew when to water by the pot being light, anyhows it looks like straight up N, those look like you can get away with a grow fert but go super light with it, like 1/8 lable strength, i think 1/4 might be too strong, just make sure it really needs water. also how long have they been in those pots with that soil? from the pics they look like a really light green, go gradually fert wise and she should be fine, you guys did the right thing with flushing in the first place, i got the nute burn using fox farms happy frog, way too strong for any seedling i put in, good luck bro they look good

also go easy on spraying them with anything but water, if they really dont need it dont do it, they got enough on they're plates as is, its a tough world on seedlings, on second thought i just read your mix, i guess 1/3 organic soil after its been flushed should be really weak, the plite and moss have no nutritional value, they just may be ready for a nice light feeding regiment

thanks mate! we have been a little harsh on them in the last week. overwatering..indicating the droopy leaves and sulphur over spray. Now that we flushed, we will start on a light feeding regiment once they dry out.

the first row of them look like little troopers, they should be a-ok after u feed them
