Crispy and Yellow Cola top!

[blackie9]

Hey guys, 1st time poster here. I have an indoor grow cabinet, x2 400 hps and x4 24 watt vertical cfls with 10 chemdog clones on their 9th week into flower. Using FF soil with some perlite for airation, in tera cotta pots on a 2 day water cycle. Using connesuer 2 part (900 ppm phased into 600ppm on week 8) with some bioblizz seaweed/molasses added very low dosage. Temp runs to 83 or so ( a lil high for my taste) with 30 -40% hum and sits about 12 inches from the lights. Lights are in a seperate container, divided by 1/4' glass with fans taking out air from lights and 2 fans in the box circulating air on the ladies with a squirrel cage -n- carbon filter combo for exporting and cleansing the air. Using SOG method. SO, everything was looking great until end of week 7 when i got some nut burn, ie leaf tips browning and curling up, nothing too major but did a nice flush with water with no nutes and laid off the nutes for a few days then went back to a lighter 600 ppm nute mix and new leaves / cola tops had new gren growth so all was well. Now, one of the main colas on one of the plants has the top turning very yellow/bown and is very crispy to the touch. it looks as if the top was a beautiful bud bud has dried out and crisped. Rest o the palnt looks great, other than some of the old leaf burn leftover. colas are dense sticky and super smelly except for thi one. the change in the bud is only about 1/4 inch of the top of the flower ( the whole cola is maybe 16 - 20 inches tall ). I was thinking maybe with the slightly higher heat, and the 2 400s maybe a lil light burn combined with the slight preivious nute burn might of caused this... idk.... Roots are hairy and white, no bugs and doesnt look moldy etc.... any ideas? Im ionly a few days away from cutting as my pistils have changed color though my tri's are still too clear.... Should i cut off this lil yellow part, let it go or try to amend it.... this plant isnt by any means the largest in the group and not the closest to the light and the other ladies' colas look great so idk..... This is some of the best looking, nastiest smelling stuff i have ever grown and this stealth grow is a new setup. Any advice out there?

Wen u say little yellow part, is it a Bannana look n thing? OR just natural plant material. If it'a the lattter i'd say ur right about the heat How close are they to the finfish line?

No when I said a lil yellow, i was referring to the top 1/4 inch of the cola. Trichromes are just starting to turn milky so harvest is in 2 days or so. The actual bud doesnt look gdegraded or anything, just yellow/brown and crisp to the touch. I was also thinking mold, but i dont see any hard evidence of mold at all. Buds are unusually dense though, maybe something from within? I am generally pretty familiar with mold having spent my 1st 10 years as a hydro man exclusively and dont see anything similar. Humidity has been super low past 10 days or so as well, barely hitting 30%,..... i know i know pics would be nice but no means to provide em....
Thanks for the interest..... 10 plants with 36 nice colas, some topping out at 20+ inches, this oddball has me puzzled
