This is my closet grow with a 600 watt hps. I have 4 plants, 2 kush n cheese and 2 uk cheese from souther oregon seeds. I have a ~400 cfm in the attic extracting air through the cool tube, an oscillating fan, a box fan, a small clip fan in the back corner, and another small fan on the floor under the canopy. and I keep the heater on in the bedroom room to keep the temperature between 68-75 F. I don't want mold or mildew with how packed they are, but i've done a lot of lollipopping and have pretty good air flow. its a sliding door style closet and I keep one side open and I just shut the bedroom door during lights out. I've been using fox farm nutes, grow big, big bloom and tiger bloom, and adjusting it with general hydro PH Up, and going almost exactly by the feeding chart except giving slightly less nitrogen since the kush n cheese seems to be a light feeder. I give plain water every other watering and they need watered every 3.5 - 4 days. I noticed my largest Kush-N-Cheese started getting some brown pistils uniformly across the entire plant 2 days ago. I woke up this morning to even more brown pistils, and all my others still have 100% white pistils. Note the slight nitrogen damage from me giving a bit too much during the 1st week of flower, the UK Cheese didn't get any damage from the same amount of nutes. I don't think this is why the pistils are browning because this happened several weeks ago and I have been correcting the nute situation and I just fed with plain water yesterday and the problem still progressed. I thought maybe somehow that plant got hit with pollen, but that seems unlikely in such a small space with no males or hermies around, that only 1 plant would get pollenated so evenly across the plant. Another thought is that I let it get underwatered a bit a couple feedings ago, could that have made some pistils brown? It is the heaviest drinker of the bunch and seems to dry out first
