There could be several things going on here. It could be a nutrient overdose and what you are seeing is toxicity symptoms or it might be light deficiency.
While 3 ppm PO4 and 40 ppm nitrates are a little on the high side they aren't abnormally so. You mentioned that you are adding 1/8 a teaspoon a day. I'm not sure if the plants are using all of those micros so you might be getting a micro build up.
On the other hand you mentioned that you are using 60 w CF bulbs. I don't think I have seen 60w aquarium CF lights. They usually come in 55 and 65 watt bulbs. Do you have standard bulbs or are you using spiral bulbs or some other kind of non-standard CF light? If you aren't using the long dual-bar type CF lights that most people use for aquariums then you will need to add more bulbs and specifically designed reflectors to your bulbs to sent more of the light into the tank. The aquarium lights are designed so that more light is angled into the tank versus a room type bulb that is designed to spread light 360 degrees all over a room (less intense light).
Also I noticed you have 2x 50/50 bulbs. These are not suitable for planted aquariums. While the plants can use the 10,000 kelvin part of the 50/50 bulb, the actinic part is not usable. So your total light is already reduced by 25%. If you are using non-aquarium bulbs then your light is probably reduced by 50% because of the lack of a reflector, so your plants are getting at least 75% less light then you think they are. If the bulbs are old (more than a year) then they will be less intense as well.
Also I am not sure how suitable 8000K bulbs are. The only information I can find on them is that they seem to be used more for salt water. I can't find any concrete info on their spectrum.
Hope this helps. Let us know what kind of lights you have.
