White pistols turning light brown only 4wks flowrin!!! help

ive been flowering now for going on 4 wks and everything has been fine, but ive noticed that the white pistols are starting to turn light brown, but overall they look burnt. im using a 400 hps and is one ft above the plant. i cant remember the last leaves ive seen on it that have looked burt or even discolored for that matter. the temp is around 80 during lights on, and 70 night. i use the floragrow,micro,and bloom all according to the dirrections. i have sprayed it with a diluted nute mix, and may explain this, but i dont see new ones growing in.. overall the plant is still filling in minus the pistols.. help?

The hairs go from white to many diff. colors from red to orange to pinkish as they flower. Some varieties start sooner and some later. Unless you are spraying them or there is a male in the room it should be fine. Let the plants run their course and relax.

I wouldnt mist during flower or when the lights are on.

You may introduce bud rot, any fert will flavour the buds, under lights and heat water concentrates light and also as it evaporates leaves highly acid or alkali salts which all burn leaves and dry them.

Like I said I did spray them a couple days ago.. If it is that should I expect a good cropping still or what.. Its still growing healthy for the most part.

Yeah the spray is prob. what did it. Your grow should be just fine. Stop spraying and let them do their thing.

Fingers crossed.. Should I expect to see the pistols growing back or she just going to bud out now?
