How many pinkies do you feed a six/seven month old corn snake per week?

Ours would have eaten loads. A corn snake of that age should be on fuzzies at the very least. The size of the prey should be slightly smaller than the width of the snake at its widest point and the snake should start with one and as it starts to keep hunting after feeding the amount shoud go up, so if you feed your snake two fluffs and it is hunting for more than a few mins after the feed give it three next week, up to about 8, then it should be able to go on to larger prey and you start at one again.
