It sounds like it may be overfermenting if its separating that much into curds and whey. When it separates like that in a short amount of time, it tends to be thin. It can be tricky this time of year to get that buttermilk consistency because it usually has more yeast with the heat and yeast contributes to a faster & thinner ferment. If it ferments slower, cooler and more bacteria rich, it will be thicker and take longer to separate into curds and whey. Regardless, it does sound like its overfermenting, so I would recommend cutting back on the amount of grains used or increase the milk. Just a small amount of grains can ferment quite a lot of milk in the summer time. Also try finding a consistently cooler spot to ferment if possible. One method to get it more bacteria rich and thicker is to let it oveferment for a couple or so days at room temperature. It can help the bacteria catch up to the yeast. When you go back to the 24 hour schedule, it tends to be slower & thicker.
