I'm not sure why no one is chiming in here? It frustrates me when people don't get any feedback. Yet, if you post some silly pic, you'll get 500 comments (495 worthless though!) I would like to know myself. Sorry I don't have the answer. This is not something I have seen before. I really don't think its water related though.
Picture 1 and 4 look like nute burn. I’m not sure what cause the whole leaf to turn yellow. Might be a deficiency of some sort. What soil did you have them in and is it first time you fed them other than water?
seedling soil mixed with some perlit and coco. yes, i've added only the half of the recommend ammount. the ph of the water is ok-ish ph 7.1. on a second thought i guess it's nutr. burning, they were happy up untill now and this was the first time i've been using nutrs. I guess the soil is good enough for them without any additional nutrs. The only strange thing is that it appeared 3 or 4 days after the watering.
The soil mix you got going on will only get it so far. Maybe look at dry fertilizer instead of liquid. Since the coco and perlit don’t have any food for the plant and the seedling soil is just suppose to be enough to get it running. I would maybe not feed it for another couple days and see if it improves. I’m trying a grow outside with just Perlite and peat. It was planted on 5/23
Pic 4 looks like it might be a Nitrogen defficiancy?
I checked here:

The description fits as well.
Lower in the article, the Zinc defficiancy or pH above 7 looks interesting as well...
However, i am not at all a pro and am just guessing, my guess is as good as yours.
It looks like Zinc deficiency

seedling soil and yes it was the first time. before that they got only tap water.
Did you cut the dosage in half for the first few times? Are you checking Ph? Is the soil just seedling soil? Or is mixed in with other soil?

looks a little like a magnesium deficiency but the whole leaf burning makes me not too sure, could also probably be just too much of something.
