Not too unusual but somewhat in that this is an odd cold bath developer.
Usually a cold bath developer has the pot oxalate and pot monobasic
phospahate in a 2: 1 ratio such as 150 gms of pot oxlate and 75 gms pot
monobasic phosphate to 1 liter of water. This one is 7:1 and diluted 1:1 to
boot. Interesting. The grain problem may be in the developer. I'm able to
produce at least 5 paper grades of difference in contrast in one negative by
using two different developer formulas, neither of which is pumped up with
an oxidizer and neither is grainy.
