Sounds like you've got your Diatoms finally! Diatoms or Brown algae are very common in newly set up tanks, new as in around 6 months of age or younger generally. The brown algae will bloom for a few months, usually three at the most and then die off when they've depleted themselves of nutrients. The green sounds like regular green algae unless it's difficult to get off then it is Green Spot Algae or GSA which I find tends to come after a Diatom bloom so you most likely just have the regular green algae.
There isn't much you can do other than wait it out and remove the algae from surfaces if you wish it, if you don't care then just leave it. Although you should rub the algae from the leaves of your plants so it doesn't choke out your plants. The feeding shouldn't really be an issue. I recommend getting some fast growing plants like Water Wisteria and Anacharis which will battle the algae for nutrients and they generally win the battle so it will reduce your algae count ^_^
As for your light, it's not the wattage per gallon that you need but rather the color of the light. LED's generally will give you a low lighting situation anyway unless they are high end LED's from Finnex or someplace else who makes them specially. Wattage is only the amount of electricity it's using so LED's tend to have around .3 watts per little LED bulb. My Finnex Fugeray Plant+ has around 9 watts total I believe but it does a whole heck of a lot more than an Incandescent at 10 watts per gallon.
Part of that is because Incandescent's are just no good for planted tank and also the color of the bulb. Ideally you want 6,500 Kelvin rating or higher for a planted tank. Kelvin ratings are the color temperature of the bulb, 6,500K is the temp of the sun at it's peak in the day when it's nice and clear out. 5,000K is like a cloudy day and then the lower you go, the worse the lighting. You can go higher than 6,500K as well although you won't find that in Fluorescent lighting generally but you will in LED's they'll just be quite costly so it's easiest to just stick with 6,500K CFL's from wal-mart or something.
