Sounds to me like it is not fully inoculated yet. I tested mine at 30 days and it claimed to be low to normal fertility on N, P, and K tests. Keep it moist and use a fungal inoculant. The pH will vary wildly while it is cooking. The colonies have to balance the different forms of nitrogen (nitrite, nitrate, and ammonia). If it still is not balanced in a few weeks - go ahead and add a little bit of lime.....a little bit goes a long way.
