Those are calyx's with pistils sticking out. It's a sign that they're ladies.

Once the pistil(s) catch and transport the pollen down into the calyx, the embryo (seed) forms and the pistils die. Only takes a few days to a week for the seed shell to start to harden. Carefully break a calyx open and see if there's a hard little minature seed in there.

But you do seem to have a ph issue and on overfeeding issue. Being this close...no more nutes and properly ph your water. Might be the ph of your soil taking a dive though, which is fairly common in late-flowering. You can compensate with slightly higher ingoing water ph.
