pistol tips turning brown on 4th week of flowering

ok my buds are for sure not finished and for sure did not get polinated....they've been doing great and budding just fine in last 2weeks, now im noticing that the tips of all pistols are turing brown...any suggestions to the problem and hopefully they are not done growing,,sorry not a good enuf camera for the rite pic so i didnt bother....buds are like size of quarters and hoping they're going to get bigger.and they are in the ground

Mine are doing the exact same thing. I wouldn't worry to much about it unless your breeding. All pistols do is grow seeds.

dont worry its natural. pistils turn brown and new ones grow through out the flowering cycle.

they catch the pollen. the seeds grow in the calyx's, pistils are like antennas.
