I put some root tabs in 13-13-13 not too long ago, dont recall if it was before or after this started. i'm also injecting a low amount of co2. thats about it.

It looks like diatoms, how old is this tank?
Has this tank undergone a mini cycle/full cycle recently?
Supposedly if your tap water is high in silicates then it can cause a bloom also no matter the age of the tank, no idea how true that is though.

I had something similar and I believe it was caused by excess phosphates, threw in a bag of phosguard in my last canister cleaning and it really helped. Though im really no expert and testing your water would be a good place to start.

What root tabs? The specs you gave make me think they aren’t even made for aquarium use and probably just dissolved and flooded your tank with phosphate and nitrate.

What substrate do you use? I have got the same issue, changed to ADA amazonia soil 3 weeks ago, just assumed its small particles from the soil as it rubs off quite easy and new leafes arent affected. Or as others mentioned might just be due to the new tank set up. Dont think its phosphates as my levels aren't too high.

Looks like diatoms to me, which are very common in new setups. If they appear in an established tank then there's some sort of imbalance going on. High Nitrates/Phosphates can be the cause. Test your water, if you have high Nitrates then do more frequent water changes, and eventually it should become less of a problem. There's yellowing on some of your plants which indicates some sort of nutrient deficiency, you could look into dosing liquid fertilizer and some root tabs for the swords and other stem plants. Some kind of algae eater could also help with your problem, amano shrimp and otos have helped in the past, though otos require a more established and balance aquarium in my experiance.

It could also be green spot/dust algae, which I've seen turn a darkish colour in the past. If so, then doing more frequent waterchanges and cleaning would help. It might also help to reduce light exposure time and intensity, floating plants like duck weed can help if you have a non dimmable light.

The tank has been setup for two or so years, I do a 50 or so water change every 3 weeks. The root tabs are those Dynamite diy, and I only used about 4 of them in the 50 gallon.

You should be doing a minimum %30% water change weekly . That will cure a lot of problems .

My wife says if I get one more aquarium she is going to leave me . I sure am going to miss her fried chicken .

That would be diatoms, here's some info on various forms of algae. https://greenaqua.hu/en/alga-tajekoztato
