HELP!!! Hairs burning?

I have a Uk cheese clone in its 5th week of life in my closet, just over 1 week now in flowering (12/12). It is under 10 cfls with a total of 17,500 lumens. The plant looks great, and getting tons on little buds. BUT in the morning when the lights come on, her hairs are long, and whitish clear. During the light period of the day, the hairs shrink up and turn rasberry colored. my lights are about 4" from the plant, and have almost no leaf burn, no stretching anywhere on her. all nodes are about 1" apart. no chem burn. Are my lights too close? The interior buds dont seem to turn so fast. Too much heat? I get up to 85 F. during the day. I added a squirrel cage fan today to exhaust. I am afraid that I will end up with some rotten cheese. I have pics of her on my profile album, I dont know how to add them here

Probably due to that heat. 85 is about 10 degrees hotter than ideal, and the pistils are VERY fragile. Touch them and they go brown, blow on them too hard with a fan they go brown, humidity too low, they can go brown, hit them with pollen, they go brown (BAD!).My guess is that heat is too much for them to handle.

85F Is your main problem imo, also as Spicy Said they are extremely fragile, my ex squeezed every damn mango bud on me once 5 weeks in 12/12 and you could clearly see where did the pistils all turned in the exact areas!. I NEVER EVER let my flower room go above 72-74F Last few weeks I run 55F. more circulation/venting. CFLS in numbers can throw off alot of heat too.

I wired in my squirrel cage fan into my attic and left my windows open last night, I awoke to her basking in 72 F. and will attempt to keep it around that. I also backed off my lights another inch or so. It has been many years since i had a grow, and am obviously a lil rusty, lol. Thanks for the advice.

I always have a fan blowing on my girls. Never had a problem with the hairs turning any color other than red once they were finishing up.

Fan blowing at plants = good. Plants flapping around in gail-force wind = bad. All things in moderation.

Tre- Be VERY careful exhausting into your attic. Adding warm, humid grow room air to a stagnant attic can be a recipe for MOLD. Not sure where you live, but if it's colder in your attic than in your grow room, you could potentially end up with condensation in your attic. Just to be clear, I'm talking about the kind of mold that can make you sick and damage your house. Not something to take lightly.

I once (knowingly/stupidly) moved into a house that had been used by some irresponsible growers. There was mold inside the walls and in the attic, where they had exhausted. The end result of living there for a year was chronic sinus infections which lead me to need sinus surgery.Mold is bad...

I am in a california desert, humidity is maybe 15% on a bad day, and 23% at night. our nights are into the 40s, and days in the 60s or low 70s, so I believe i am ok. I have a box fan blowing low up and across her. she moves a lil bit, but it more like a light breeze.

some people dont give the plant enough nitrogen during flower and some growers give too much N during veg, both do fucked up things to your flowering cycle

I would agree with others who have commented on the heat & light issues, 4 inches is probably a bit close for that amount of lights. Just back them off a bit, & try and keep the temps down as much as you can.

I backed the lights off a few more inches and wired in the squirell cage fan. I stayed around 72-75 most of the day, peaking at 79 just before dark (I am also leaving the windows open in the room to bring in fresh cool air). most all of the hairs stayed whiteish except for the top, i am going to adjust the top lights out a couple of more inches and see what happens.

anyone have any info on distance and lumens loss on cfls?

I don't want to get so far away that she starts stretching. I have found that UK cheese will reach around 6 ft. high indoors, and that is all i have.

Can't comment on the lumen output as you have only stated the quantity of your bulbs and not their wattage. As CFL's are not that powerful to begin with, the loss of usable light will be greater if you misjudge it & place them too far away, but you know that.

I have the following:
7 x 23 watt 2700k at 1650 lumens each =11550 lumens
1 x 25 watt 2700k at 1600 lumens
1 x 26 watt 3000k at 1700 lumens
1 x 42 watt 2700k at 2700 lumens
= a total of 17500 lumens

my lights are 3 on top, and the other 7 are dispersed a little lower around the perimeter.
the top lights are 1 foot away, and the side lights range from 5" to 9" away.
they were closer, but i was building too much heat and turning the hairs rasberry colored. that problem seems to be solved, but now I am concerned as I don't want to get the lights too far away.

All houses have attic vents. All houses. Sealing an attic is an idiot's endeavor. So, vent up to the attic but take that vent line and add enough dryer vent hose to reach that attic vent. Clip the thing on, who is going to know? Just know that the longer the line, the more pressure it takes to move the air along. A booster fan mid-line in your attic run can solve that problem. Additionally, there is "hard" dryer vent pipe. This is a HUGE improvement in air flow versus the flexible vent hose. But bottom line in this is you are spot on advising against venting INTO the attic. A setup for a mold disaster in short order.

Glad moving the lights stopped the worst of the heat build up problem, now you just have to find the sweet spot for the distance, as 5" to 9" is probably a bit too far away for CFL's . Have you got much air movement in the grow area? Because if you can keep the heat down around the CFL's you can get them a lot closer, without causing problems like bleaching as you would with an HPS lamp. Any fans?, (cant remember if you said or not)

I am in the California high desert. I do not have a duct on my attic exhaust fan, but this is a very small grow (I will have a rotation of three plants. 1 vegging, while 2 are flowering, hoping for a 1 plant harvest about once a month). Our humidity is so low here, nothing molds, plus it is a small, but extremely high rpm squirrel cage fan and my attic is very well vented with 10-20 mph winds flowing through almost constantly. I am not trying to justify my setup, but to lay it out for all to give there opinions knowing my situation and geographic location. please keep the advice coming. I have never tried UK cheese but have heard nothing but great things about it. I want mine to turn out well.

I have a box fan blowing on low across the plant, and angled a lil upward to get a flow across the lights and up towards the exhaust fan
