2 week old cannabis plant from seed

First grow, possibly overwatered 2 week old seedling, or too much nitrogen in soil

neuromorphic

Hey all. These are photo’s (mazar). They are just under 2 weeks old since germinating. The soil is miracle grow potting mix. I am using a 225 measured from wall HLG 225 Elite LED. Up until 2 days ago the plants would have their leaves pointing upwards towards the light and looked generally healthy. I was only using a small amount of water like just dripping it on the soil with my hand, probably only 25 to 50 ml at a time once every couple days. I thought that maybe they could use more water, so I decided about 5 days ago to give them 1/2 cup of water each. The PH of the water is 7.1. I watered another 1/2 cup 2 days ago, then they started appearing more and more sickly and droopy. I am assuming the issue is overwatering and have backed off now. The humidity dropped the last few days outside to around 30% (abnormally low for where I live and won’t be back up for a couple more days). The temperature is about 74 by the plants. The light is about 28″ above the plants.

The leaves appear to have possibly gotten too dark green? The photo where they are smaller is right before I started giving them the extra water. I put the other plant by them to try to help raise the humidity along. Thanks for any advice.

alright so let me start off here: I germ all my seeds for about 2-3 days in a wet paper towel and then when the root is a few CM long i plant it a few CM down in 1 of the pots that you see. Also, I am using Scotts Potting mix Hyponex as my medium. I also am using a 400w MH light that is on 18/6 until flowering when i will switch to the HPS. So, this is ultimately my first grow as you can see. My grow location is a closet as you can see. So the plant that is worrying me is the eldest, which is roughly between 2 and 2 1/2 weeks old since germination. I havent given the plants ANY nutes yet. (I have the fox farm trio for when they’re ready) but yeah thats pretty much it, and as far as the distance of my 400w MH from the plants, i put my hand over the tallest one (in the middle) and my hand was basically just kinda warm, not too hot or anything. but yeah ive read alot about not freaking out over small problems with seedlings, so the leaves have been around this color for the last few days and growth looks like it has slowed QUITE a bit.. so heres my question. why the yellow leaves? oh and also it shouldnt be an over watering concern, because for the first few days the plants were in soil i only sprayed the soil making sure i didnt water too much, and now that theyre all planted i started pouring water in just until i got a small runoff, thats IT. Also, to the left of the plants in the pics i have a fan that i can either aim at the plants or at the light for cooling and i also have the exhaust fan in the pic as well. and only water it once the top soil looks pretty dry.. I havent been taking the PH of the soil because i dont have a pen only a little test kit but i assumed for the better part i was doing everything pretty good. so am i doing something wrong. or did i post this for nothing and im actually a fuckin great marijuana farmer. lol

FYI. the strain is AK-48, if you cant tell by the color of the pots. the two closeup pics are of the same plant. all help would be appreciated it.. if i forgot anything lemme know

how is it way too hot if i put my hand over the top of the tallest plant and my hand didnt even burn a LITTLE bit? and its almost like its a mixture of soil and a little bit of like mulch or something. but the back of the soil bag says it has nitrogen, perlite etc, nothing like out the ordinary

and why is the OLDEST plant yellow and the two that are even younger still like a deep green color?

edit: ALSO, the soil around the plant in the pics is actually right after i watered it a decent amount
