This isn't true at all I'm afraid - you're somewhat confused and giving out incorrect information.
The ovules or calyxs or seed pods of a female Cannabis plant are parthenocarpic, which basically means they'll behave in the same way as if they've been pollenated and seeded regardless of whether they have or not. This is why the calyxs swell to the size they do on unpollenated sensimilla or seedless female plants.
Pollenation of the ovules or calyxs does NOT stop resin and THC production at all, it simply carries on as if the calyx had not been pollenated - this is the plants method of protecting the seed by a layer of sticky resin that deters any predators or insects from feeding on its seeds, and it also helps the seed pods from drying out from UVB exposure.
The resin is produced on the calyx to protect the seed - resin production does not stop at pollenation.
What does happen is that the plant then re-focuses it's energy on seed production and slows down the production of other flowers of calyxs because its genetic program is to produce seeds to complete it's life cycle - that's why unseeded sensimilla put all their energy into producing as many flowers, buds, ovules or calyxs as possible in a desperate attempt to get a least one of them pollenated and seeded.
The pollenation of half a dozen calyxs won't make much difference to the yield, but with more extensive pollenation the plant switches energy into seed production and the yield will suffer as a result.
But none of this has any affect whatsoever on resin production.
