Help!!! This is my first grow and wondering if anyone can tell me what would cause the plants to look like this?

These aren’t the best pics had my friend take a pic because I was at work but will update with better pics soon as I get home

So here’s what we need. Btw the pics look ok.
Grow details as many as possible. Looks like dwc so let them know that as well. Nutrients given, ph, anything you can think of.

This is a dwc grow I’m not sure the exact date but roughly 2 and a half weeks from seed. I don’t have a digital ph meter but using the drops from general hydroponics my ph is between 5.5 and 6.0. These are both auto flowering strains and I have the Mars 1000w led that I just put in 4 days ago (originally was using the small “blurple” light that came with my grow tent (32” x 32” x 54”). Im using flora trio nutrients and cal mag plus. Thursday I did a water change and each bucket has about 3.5 to 4 gallons in the res and I added 1.5 tsp of each nutrient (gro, micro, bloom, & calmag). I used filtered tap water and the ppm of each res was less than 10 before I added the nutrients. I also have 2 extra buckets and air stones so I let the water bubble for a good 18 hours before I moved plants into the fresh nutrient water. My temps inside the grow tent have ranged from 72F up to 89F when I first got started but I installed a window unit ac in the room which has kept my temps consistently between 70F and 77F.Only thing I did differently this time is took some water from the res and squirted the top of hydroton to make sure all of the roots were being fed as also sprayed the leaves a little and I’m wondering if that was an issue

They look ok to my rookie eye by the way. I have a question tho... Wouldn't humidity domes be needed still at that stage for more rapid growth like when growing in soil? I'm still new to growing myself and just had that on the brain if you or anyone can help.

Here are better pics that show the discoloring of the leaves (mainly on first set of true leaves)

I would like to know the answer to this too? And if so when should the dome be removed?

I'm new to hydro as well, I would make sure that you are following the nute schedule. What are your ppms after adding the nutes?
