Orange/browning dried up pistils day 27 of flower

I've had pistils start turning orange this early in the past but it was from light stress. This bud is about halfway from the top of the plant's canopy and the soil. Definitely not light stress. Just looking for multiple opinions on what could be causing this. Using Athena pro nutrient line with Botanicare CalMag, Power SI & KoolBloom to use up what is left of the old nutrients line. Feeding chart is below. Flowering in 10 gallon pots in pro mix & worm castings, 2k watt LEDs, CO2 generators, the tent been at a constant 80-83°F & 45% RH or lower. Running a consistent 1450 ppm this is the only plant out of the 4 in the tent showing these signs

My apologies for all the words just trying to supply as much info as possible

Hmmmm. Curious . what have been spraying on them for ipm and or foliar feed? Micro climate in the room?

Been using Lost Coast Plant Therapy (2 Tbsp/gallon) to get rid of a spider mites infestation I had in January. Heavy spray on all tents about once a week to make sure they're gone. Climate is very consistent throughout the tent, it's only 8'x4'.

I'm attaching a newer picture of the buds. Newer sugar leaves started curling down around day 30. Makes me think it's nutrient burn but I want to be sure

The only time I see the weird looking leaves is a reveg or excess N during flower, but Iive only been doing this a year and a half. Doesn’t look like reveg so my guess is too much N

I did have a SINGLE day where one of three lights in that tent flipped back to an 18/6 light cycle because of a programming error on the outlet timer, but that was over 2 weeks ago and it was caught very quickly, like, so quickly I figured it wouldn't even be an issue.

Plant therapy is isopropyl based can burn them pistils! The plants are eating up that c02 but looks like you can lower them lights a bit. Only do so if you have a light meter and are comfortable with it. Maybe turn back the gas a hair and adjust on vpd chart accordingly. Just my 2 cents
Cheers

I was considering this as a possibility, but it's only happening to one plant out of the 4 in the same tent. I did some digging and I'm confident it's just too much N ): got some foxtailing that started happening today but thankfully I've already adjusted the feed starting today, just hoping they will still fill in all the gaps they've created. Here's a pic just to keep everyone updated.

Strain is gelato 33 in case anyone is wondering

Another thing that can cause prematurely maturing pistils is pollination. I had the same thing happen years ago and was super confused until I realized that one of my plants was throwing tons of nanners and had thoroughly pollinated itself and the plant right next to it. Check for nanners or developing seeds. I've heard wind burn can do it as well, but have never seen it myself so take that for what it's worth.

Wind burn would make sense. I put in a standing fan about 3 days before I noticed the buds browning in the original pic. Changed the feed and environment I'll just have to wait til next week for more results. Crossing my fingers that I'll be able to salvage a few ounces out of this
