Asking for help with those specific problems (the taste was your cannabinoid source, they are not all created equal) will get you where you want to be faster than waiting for someone to run a class I would wager.
Without added cannabinoids? First one gets the kitchen witchery on point, then one adds drugs…
Mold suggests insufficient osmoticum (not enough sugar).
A search such as Search results for 'Gummy preservative' - Future4200 or even explicitly asking “HTF are you guys keeping your gummies from molding” are both decent approaches.
Are there no new question?
No, but there are certainly a bunch of common ones that have been explored, and folks who might help you find them if you seem to be putting in the effort.
