need some help please

Hi guys got 6 plants going they are 15 days old.
used 50/50 coco/ perlite
ph 6.0
T5 8 bulb agrolite was 8inchs raised to 1 foot
75 F 45% humidity
At 7 days gave them 320 ppm nutes(102ppm water plain)
They was burned the next day so flushed them with plain 6.0 water.They have been recovering fine just not these 2 northern lights by royal queen seeds. Barneys lsd looks fine as u can see in pics.\
Yesterday gave them 219ppm 1cc botnicare pro grow , 1.5 cc cal /mg and .5 silcan blast. Could have game more nutes but wanted to stay under 250ppm.

Please help!!!!

have you kept the medium moist the whole time?

I let it dry 4 days then watered

they look waterlogged, seedlings aren't my strong point someone may have better info. You have holes in the bottom of the cups I assume?

yea got holes him them I let them run off 20%. My lsd look just fine as u see in pic

I'm no expert but they look starved to me, I see no evidence of being overfed. A 50/50 mix is very airy - I don't think you could overwater with that mix I do 70/30 and by day 4 I feed 1/4 strength nutes daily.

so should I water them tomorrow with stronger nutes and how much ppm do you think?

I don't own a ppm meter so I can't tell you what it would be - I just do 1/4 strength of the recommended nutes for two weeks, then up it to 1/2 strength. But yours are way behind what a 15 day old plant should be in growth so if it were me I would definitely feed 1/4 strength put your T-5's about 6" from the top of the plants. I see that you are new - welcome to growing. I attached a pic of a 2 week old seedling under t-5's so you can get an idea of growth when conditions are good.

Never let coco dry - it should always be moist and each feeding should have run off everytime With your mix it can't go too long between feedings even with that small of a seedling. Start with every other day for a few and see how they look. When you transplant I suggest a 70/30 coco/perlite mix - it will retain more moisture which is important when the plants get larger.
