Love the scape, but as for growth issues it's tricky.
My gut feeling says still more light...for the carpet plants at least. The crypts look pretty happy and not in a brightly lit growth form now whereas in higher light (carpet plant levels) they will tend grow rather more compact and darker. As a safe test you could try positioning some of the struggling Hemianthus micranthemoides into more light nearer the surface and see if grows more strongly over a few days.
Yes light encouages algae but algae will also take hold on plants struggling with lack of light. It may not be relevant but my tanks seem to do better without Easy Carbo...
