The rule of thumb is generally 7 days, ideally with a little moisture in between. However with a sandier. Low OM soil you might be OK in 3-5, but there is still risk there. In my area we are typically silty clay loam with 4-5% OM and I know guys som etimes only weait 3 days and get by with it. If it were me I would use your 32% option or look at a side-dress application.
