Trouble with my plants... please help!

So these babies are 15 days in veg. But some of them has yellow spots on their leaves. The soil is some peat moss mix, with sand, etc + I guess there are some ferts added, because I see little fert balls. pH is 6.8-6.9 for soil and the same for water I use. You can see the yellow spots in pics: 1.-5. The yellow spots are on new leaves too, even more. Pots are 4 gallon with few holes in the bottom. Even though pots are pretty big there are some roots sticking out of these holes...
So this is the first problem. Another one is with this one plant whose leaves are shrivelled up. You can see in pics: 6.-9.

Please, help me heal these babies...

Pics 6.-9. are here.

Maybe a difficency in NPK?

a yellowing of the leafs usaully means there is a magnesium dificiancy
which can be sorted with epsom salts

I haven't used any nutes yet, it's only 3rd week. But I bought 6-6-6 NPK nute for veg. Is it ok? I wasn't using any sand, I bought the soil at the store, it is some kind of tomatoe soil with 6,8-7 pH. I was watering every 2 days when the surface of soil (about 1 inch) was dry. With about 1.5liters. After last watering the water was dripping out of the holes so I haven't watered it since, because I am afraid I could be overwatering. Growroom is about 80-86F hot. I am using 250W HPS with cooler and 2 CFLs about 20W each. I am keeping HPS about 7 inches away.

What do you think about the second plant?

Utax..

you plants look good....

I know you see a problem but at this point it can be anything..
From what I can see you growth and your color are excellent.

These spots can be caused buy just a section of your roots going through a PH impbalanced part of the soil.. or a heavly nutrient saturated area..

Please post a picture of the entire plant..

Yeah, Garden Knowm, I tought about soil homogeneous too. Maybe, that's the problem... I hope it goes well... :stoned:

This is how the one of them look. They all are pretty much the same size, about 7''. It's 15th day of veg. I think the growth rate is decent?

Utax... Looks darn near perfect...
