White hairs on buds turning brown too early

[BBD32]

I am in the 5th week of flowering and some of the white hairs on my buds are turning brown already. I wasn't sure if this was normal. Also I noticed that the buds affected are closest to my oscillating fan. I tried taking pictures but it's almost impossible to see in the pictures because of the hps light.

Temps are 70-82
Humidity is 50-55

The only thing I started doing differently is adding general hydroponics bloom nutes. No sign of any burn though. I'm a little worried since I read somewhere on here that it could mean the plant is turning Hermie


Any thoughts?

At five weeks into flowering I would expect pistils that were turning brown.

yep nothing wrong with that completely normal, exceptions are yes the fan is prob killing the affected pistils as does touching them with your fingers but at five weeks flower the plant would be showing some expired pistils.
