No outside linking, gotta upload to the farm.
I would, in a heartbeat (and have). I don't think it's hermies in this case, for some reason, though.sorry dude but in your case id hope for a hidden herm in the lower nugs mites are truly a growers bane. you can check some of the calyxs on the lower nugs for a seed developing. spraying your plants with cold water 30 to 45 min before lights on will neutralize pollen but i wouldnt do that past the 5th week imo.
its hit 90 once maybe twice that i know of. any other time its been high its got up to the hight eighties. but my goal always is to keep my flower room under 83 and no lower than 75 for the day period, but these really hot colorado summer nights makes it very very difficult to keep it down under 85 at timesare you hitting 90 plus?
when you say co2 blast, can you be more specific on what actually needs to be done?I' ve had the co2 burn, ripens the hairs overnight.But that was with a manual co2 set up, if you give them a big blast of co2, and it doesn't have to be for long. It will flip those hairs quick.
The low temps and high humidity sounds like it could be the cause. Plus you have a 20 degree diff between lights on and off. The low temp at lights off, i use to finnish, helps ripen my babies up.plus can bring out color. the moisture in the water will cling to the hairs and low temps will put a hurtin on em. your at week 4 you do not want the cooler nights yet. but 61 is not too low, its the 88% humidity...yowza
Thing is it usally takes longer to show with the cooler temps, the 12-20 hours fits more with the co2 burn. no co2 leaks?
whats she smell like? and new growth? new hairs?
mites dont normal effect the hairs to turn.
High temps you usually get leaf curl.
Just seen the pics, the leaves look ok, doesnt look mite infested.
Is it occuring on tops or all buds like some lower tucked away buds?
Dub you said that the browning of the pistols is on the lower part of the plant and you also mentioned that they were big girls.
I have noticed in the past that when i dont skirt larger plants with a dense canopy sometimes the lower pistols turn red or brown early. Which I assumed was due to lack of light penitration.
If it is only at the lower sites you may in the future just want to cut out the shaded areas. But I would like to see a picture of the whole plant and its density up top before making that recomendation.
Had the same thing happen to me when I first got my new room up and runnin. The new Blueprint CO2 controller my local store recommended took a shit and dumped an entire 35lb bottle overnight leaving the few plants I had in the room sitting in 8000ppm + CO2 levels overnight. The hairs turned brown and looked like they were trying to mature minus the resin and full buds. The younger plants were able to bounce back but the older plants never did. MGGI' ve had the co2 burn, ripens the hairs overnight.But that was with a manual co2 set up, if you give them a big blast of co2, and it doesn't have to be for long. It will flip those hairs quick.
