Welcome to the forum! You are at the most helpful, friendly bunch of stoners you’re going to find on the 'net.
So; a couple of things first off: I would advise placing red cups over the clear as the roots do NOT like light. The soil looks to be quite wet so really suggest letting them dry out. You want to water very little: like a teaspoon or so and keep a dome over the top. The new seedlings have no tap root and extract all of their moisture initially from the air. Misting the inside of the dome a couple of times a day will help greatly. This is what most of us do.
Soil: I would advise staying away from any product that has added fertilizer like Miracle Grow. If the package says: “needs no food for 4 months” or “moisture control” it’s not a great choice. The reason is the fertilizers used can be tasted in the finished flower, producing a harsh taste. Fox Farms is popular and Scott’s along with others have good organic lines with bat guano and worm castings etc.
PH: you really want to control the PH of your water going in. This includes any nutrients or supplements you may wish to use. A digital PH meter is the surest way to measure accurately. Soil probes are worthless, drops and strips are not as accurate as you’d like and inconvenient as well.
Here’s a good one that can be calibrated. I use this one and others have as well and like it.
Lighting is critical and is the least understood part of indoor growing. Beware of the Amazon “blurple” lights as there are many many much better lights out there that are less expensive to operate and do a better job. They will fit right in to your being tech savvy. Here’s the thread you want for lighting:
