They don't look all that bad. I'm confused though why the heat mat control is set for 70 but your reading is 79? Are T5 that hot? I don't feel you need 200ml water per plant. It depends how much that seed mix dries out, but in plastic cups I don't think it will. I use the same cup. I guess you got holes drilled in the clear one but not the red one? My math says 200ml is like 7 oz (7 shots). How long before you rewater? It all depends, but I would try only 60 ml per plant and it's a guess but I would not be surprised if you could even go a week before watering those again. They don't look like they can drink that much. But they look ok to me anyhow. If you look in the clear cup and see water droplets midway down you're still ok in my opinion.Ok guessing water problem let medium dry out before watering and gave them 200ml of ph 7 water. On day 10 of life root systems look fine getting some cupping/twisting and just starting to get some slight yellowing on the tips of the critical sour deisel. Heat mat is still set at 70 to keep roots warm when night temps drop. If I didnt have the heat mat on the hygrometer would read 59 as a low. Fan was hitting more of the plants than I would like useing it more for heat displacement from the t5. So I moved t5 up a couple inches and tilted fan back right now. Soil is a seedling mix npk 000. Mixed with worm castings and perlite. Approx measurements 75% seedling mix with perlite. 15% castings and additional 10% perlite. Here are some pictures of the worst couplrits.
