I noticed a small amount of mold (or mildew) on the dry wall under my kitchen sink. I don't know how long it's been there, or how long it's taken it to get there, but I cleaned it up with some disinfecting clorox wipes. Is it possible some tiny amount of water go through the part where my faucet meets the counter top? If so, is there anything I can put there to stop it? See photo.
Thanks!

Caulk may work to some extent, but silicone is soft and doesn't withstand movement terribly well. I'd check whether there's a seal missing at that location. Maybe it was installed in the wrong position.
If not, I'd install a thin rubber or silicone washer. This would mean disconnecting the faucet supply lines and removing the mounting nut, but it will result in a more reliable seal than caulk.
Otherwise, definitely use pure silicone caulk and not latex, which won't bond as well and tends to harden over time, which will result in cracking and failure.
