Need help with algae ID

So I've got this algae problem...

I have some BBA popping up on many plants, and an algae that I think is spot algae covering many leaves on my swords and crypts. It's also growing on the glass and my stones, and even beginning to grow on the substrate. Here is the algae in question:



And on the rocks...



I'd like help with ID so I can properly attack this issue.

The algae must be scrubbed off any objects its on and is impossible to remove from plants without removing the leaves. My tank is beginning to get overrun and is no longer a satisfying and relaxing hobby at the moment.

I plan on attacking this with frequent water changes and stopping ferts for about a week to maintain near or 0 nitrate levels, hopefully starving out the algae and "resetting" the water parameters.

I thought that clado was more stringy. This algae is a soft, fuzzy type of green algae.

Tell us more. CO2? Size of tank, lighting over the tank, how long lights on? How long tank has been set up and what is the water like? How much and how often do you do water changes? What do you use to fertilize the tank?

I thought the image was enough for algae ID, but I can easily give more information!

30 gallon tank, with no CO2, dual T5 21 watt lights on for 7 hours with a 21 inch LED strip running for 3 hours. The tank is over a year old and the water levels are all normal except for nitrates, which are quite high around 60-80 (the test kit is not calibrated though). I do a PWC of 30% once weekly. I am fertilizing using a standard PPS-Pro recipe.
