Help me green up my plants

Some of my plants aren't as green as they should be. In fact, so are down right yellow or brown.

What is most likely causing them to yellow?

I does PMDD and dose nitrates and phospates as needed. I just started with the PMDD a few weeks ago and am dosing lightly to start.

I have a POS Carbo Plus cranked to the max. A new full pressurized system will be delivered Monday. So if CO2 is the issue, that will be corrected soon.

Here's a couple of pics to show you what I am talking about.

30ppm co2 will make a big difference if your lighting and ferts are in order. You gotta take a wholistic approach to this thing. If one ingredient is in short supply, wether its ferts,light,or co2, the plants will stunt eventually.

I suspect that the CO2 thing must be it. Though I will increase ferts over time. I am taking it a little slow to make sure I don't end up with an algea tank.

Some plants are really green and others aren't.

My hornswort is really brownish but has still grown a foot in the last week.
