There is going to be an algae bloom early in the process. The plants are still shocked from shipment and parameter changes and aren't out competing the algae. I believe that is part of it. You said that your plants are growing well so I don't think that is the whole story. I would look into the lighting. Aside from your timed lights, does the tank receive any daylight diffuse or direct? If so I would consider keeping the blinds and curtains in the room with the tank closed or repositioning the tank. For the timed lights I would cut down to 8 hours and clean the glass and decorations that are reasonably easy to clean and monitor algae growth. If it isn't overtaking the glass or decorations after a week increase the light by 15 minutes and monitor for another week. When the algae begins to overtake the glass and decor within the week reduce by 15 minutes back to the timing when algae was manageable. I would also consider the addition of some algae eating animal if you don't have some already and your current stocking will allow it. Many snails prefer algae above all else and will actually "clean" algae off your plants. Lastly invest in a magnetic glass cleaner. Cleaning glass every 3-4 days is not out of the ordinary for a planted tank. Cleaning the algae off the glass forces your algae eaters to eat the algae on gravel, decor, and plants which cannot be easily cleaned. I hope this helps.
