Yellow leaves

I am a beginner to indoor growing and could use any help or feedback. As of now, I am having trouble with 3 of my Critical Purple Autos. They are starting to turn yellow and I don’t know why. I’m beginning to believe it could be nutrient deficiency? If so, what kind of nutrients should I get and from where. Please let me know your opinions and feedback. It’s all highly appreciated. Thank you.

Hello the soil I am using is Schultz Premium Potting Soil. As for lights, I am using 2 Likesuns 1000w LED Full Spectrum Lights and 1 Mars Hydro Ts 1000w LED Full Spectrum. The lights are currently about 22-24 inches above the plants. I honestly have not done any checking of PH as I don’t know much on how to go about it. I was watering them once a day due to how quick the soil would dry until this happened. Now I’ve been watering them every other day. I also have 2 Northern Light Autos growing among the same setup and they are doing extremely well compared to the Criticle Purples. Here are some pictures.

Are you running your lights at full power?

Yes, I currently am and have since they were planted. Should I not?

Seedlings don't need intense light.. Turn em down to less than half.. See if that helps..

Thank you so much for the knowledge, it’s highly appreciated. I just turned them down to less than half and will keep you updated on the progress. Do you have any advice on any kind of nutrients to use just in case I may need some? Someone told me that it could possibly be Nitrogen deficiency?

Seedlings usually don't need any nutes for the first two weeks.. Then start with 1/4 strength nutes and go from there..

Bro get a bluelab Hp and Ec meter, you gonna need it no mather in witch stage your in.
I have for my seedling 30-40% efekt on my lights (spider farmer sf1000), veg 40-70% and flower 80-100%.
Intensity of the light gonna eat upp you plants, das the welloing.

back of the light a good amount and look that your ph is 6.5 (water) whit the penn (its very easy!), and keep the humidity to a 70% in the seedling stage then 55-60% in veg and 45-55% in flower and feed them.

(THIS IS WHAT WORKS FOR ME)
Im not a expert or nothing but i have 4 plants under my belt so im pretty happy, and high as my dreams

UPDATE: So far I’d say things are going okay for a beginner (well hopefully) lmaoo. The plants are growing and some are having troubles. They’re all flowering finally. One or 2 of them seem to be doing very well or “decent” as most would say. But one is having a lot of trouble and I need help identifying why. I’m pretty sure it’s heat stress but let me know what you guys think.

Here’s a another 3 of the overall growth. Please leave all the advice you all can give, I’d really appreciate it, thank you so much.

check out the update please and let me know what you think for a beginner lol or give me some advice

Surprised nobody mentioned they are overwatered.

Your soil looks heavy and dense. When they are young water them less often and in smaller Amounts.

They look hungry. What feed do u have?

How close is your light and how much/often do you water? Temp? Rh? Feed?

I did. Back lot are stunted due to wet media. You can see the edges are all wet.

That’s a massive pot for a tiny plant.

The others have battled their way through and are now losing leaves before flowering.

Less water!
