Flowerh, it may be an algae bloom. this can happen in new tanks. Initial blooms go away after sometime as the plants take root. Why don't you run the filter and see for a week? Do not make any changes for a while.
Try and keep the set up simple, don't use the skimmer, its really not necessary.Filter and CO2 is enough. You don't have to dose any fertilizers for couple of weeks.
Haven't used a skimmer in a planted tank (I used them only in Reef Aquariums) ever since I started this hobby 15 years ago, and my plants have not suffered for it.
The other reason and most likely would be the ADA soil. I quote from their new Singapore site:
"Aqua Soil Amazonia has been used by many planted aquarium hobbyists around the world as a base substrate for growing aquatic plants. Aqua Soil Amazonia is produced from black soil with rich organic substances, mimicking the rich soil in the Amazons; improving plant growth.
But, in the alkaline base water*, there are reports of water colouring due to possible seepages of organic substance such as humic acid into the water."
Aha! So just do a water change, should be simple. Or run the filter with some activated charcoal in one of the chambers (less reccommended as it takes up needed nutrients for the plants)
