Hi, This tank has been planted for about 2 weeks now.
20G
CO2
Light on for 7 hours daily (split: 3 ON, 2 OFF, 4 ON)
EI Dosing
50% water change weekly

Recently my S Repens have started to get dark green spots on the leaves, should I be worried or is this normal for the older leaves? These were clippings btw.
Not diatom as I am not able to rub anything off the leaves.

It's most likely green dot. Just get rid of the bottom leaves that have it, they won't disappear unless you get horned nerites or removal of the leaf.
Also your stauros look a little beat, I find they are serious root feeders as I've had around 300+ stauros where most roots reached over 6" long. Your EI and gravel substrate might not be enough, I recommend root ferts or a plant substrate.
This attached image was my old carpet, went on vacation for one week and carpet yellowed and turned skinny without fertilization - very heavy feeder.

Thanks. It does look like GSA. Seems to be all contained on the plants, none on the glass yet.

I am dosing via EI, it's odd that I would have a shortage of phospates. My photoperiod is not too long and I have enough CO2 in solution according to my drop checker (indicator matches the reference almost exactly).

I added some root tabs under the plants, hopefully that will help them. I have been dosing ferts in the water column for only a week though, the first week there was no ferts added.

I don't need it has much to do with you co2 or lighting (what is it anyways?) where I think the problem might be for you stauros is your lack of fertilization in the root base. Is the tank dirted? Stauros should be growing compact, if it's lanky and stretched you mostly have a deficiancy. If the plant is healthier it would less likely have algae problems.
Issue could be your light and/or fertilization.

These plants were mostly clipping without roots when they were planted.
They have not gotten any taller since I planted them about 10 days ago.

This is how they looked when I got them:


Tank has eco complete with gravel cap.
