Buds are kinda white on the inside? Looks kinda like cauliflower

Kinda a newbie grower still after a ten year hiatus so please bare with me.

The first two cycles of my grow this has happened...I take one of the big colas and start snipping the buds off the main stem I noticed this.... Is this just due to lack of light getting to the center of big buds or something else? In the first cycle the whitish areas seem to pull out easily like a dead core....

first 3 pics are from the first cycle
The rest are from the second cycle(not nearly as prominent in the second cycle so far)


Lighting:
4 mars hydro sp3000 (dimmed to 75%)
2 mars hydro sp150
distance from canopy 16”

Environment:

79-82F day temp
67-72 night temp
40%-50% humidity
2 - 4” ac infinity fans extracting (200cfm x 2)
6 - 4” passive intakes
4 oscillating secret jardin fans above canopy
2 below canopy
2 30 pint dehumidifiers wall mounted up high

Medium:
2 parts Sunshine mix 4
1 part perlite
16 - 3 gallon pots (dry out once ever 2-3 days)

Nutrients: using advanced nutrients feeding chart....hobbyist level...typically half strength feeding (resulting in 400ppm-1100ppm) with a plain water (RO water + calmag) in between feedings...many times I’ll feed 2 times in a row if it seems like they want more nutrients.

Flowering nutrients:

advanced nutrients connoisseur bloom a and b
Big bud
Overdrive
B52
Voodoo juice
Gh calimag(1-0-0) used during plain watering(in between feedings)

veg nutrients:
advanced nutrients connoisseur grow a and b
Voodoo juice
B52
Advance cal mag (4-0-0) used during plain watering(in between feedings)

Light bleaching makes sense in a lot of ways...There is a lot of light pumping in there.... It also does look a lot like the white tips at the top of buds that form from the lights being too close but i only lever see it towards the center of the buds along the stem....is this the result of light bleaching early in flower and the newer growth towards the outside of the buds later in flower not sharing the same fate?

Honestly it just looks like the inner parts of the bud is lacking in chlorophyll for whatever reason. From what I see it doesn't look to be on the bud but part of the bud.

Exactly, caused by light not getting to the inside of the bud. It's very common for the inside of dense nugs to be lighter in color than the outside, especially if the plant wasn't pumped full of nitrogen in mid to late flower.

I sort of felt like that was the case but when thinking it through I felt like that might be to the contrary. Usually when plants need more light they turn darker green for better absorption of light and when they are getting sufficient light they turn lighter green to allow light to pass through them.
After thinking on it more though it's probably because no light gets to it whatsoever so the plant decides to produce chlorophyll in areas actually receiving light.

That isn't light bleaching and it isn't from lack of light. Not sure what it is, but you do have a problem there.

Thank you for all this excellent insight!....it does seem the denser and bigger the nug, the more prominent it is. Along some of the main colas the white cauliflower appearance was at the tops of the nug that were heavily shaded/buried by the nug above it....so light depravation does seem to play a role. Was also thinkin it could be nutrient related since I’m still very much dialing in my green thumb and battled deficiencies in mid flower in both cycles. Feared it could be early onset of budrot or something similar....

Ok so looks like you have some foxtailing and some white pistils which I have had as a response to heat stress, now of course this istrain dependent as well. The fact that it is lacking colour and has the foxtailing and pistils makes me wonder if it has ever gotten very hot in your room or if the lights are very very close to your colas (you also stated this is happening on your big colas which are closer to the source of heat (light)) . This may or may not be the cause but it's something to consider

I've had this happen before inside big/dense colas, and in spots where two buds are constantly touching each other. Dunno what causes it but it definitely seems connected to a lack of light.

Sometimes there is mold in there too, so I always inspect those areas a little more carefully, but it looks like yours are fine. (Watch out for little puffs of "smoke" (spores) when you break them apart).

It's kinda off-putting when it's fresh, but it dries to more of a tan color that looks pretty normal.

Sounds like you were dealing with the same situation.....in the first cycle I had white fuzzy mold in the middle of a few forearm sized colas amongst the discolored whiteish core.....In the second cycle I Lowered the setting on the dehumidifiers to run about 40% RH and Kept temps below 80 for the most part....haven’t seen the white fuzzy mold anywhere yet but still got some of the whitish core in the bigger dense buds. Is the fix Topping the plants a couple times so I grow more smaller buds and less big dense colas?

I’d say it’s heat stress. Your leaves are canoeing pretty bad in some pics. I also think they could have went 1-2 weeks longer.

Definately had some canoeing in both cycles....I Dimmed the sp3000’s to 75% in the 2nd cycle which seemed to help. Temps have been Kept to what I believe to be optimal for a led lit room(79-82) but time may prove otherwise. I prob do have too much light in there though....3’ x 12’ grow space with 4 - sp3000’s(dimmed to 75%) and 2 - sp150’s....on the Next cycle I will prob dim to 60% and keep temps in the mid 70s to see what happens.

I would say theres a very low likelihood this is from a "lack" of light considering the wattage you are pushing out 16" away from the canopy. There are people who grow killer weed with 100w cfl's (albeit a small yeild). Mars advertises a ppfd ranging from high 900s to mid 700s in a 4x2' square. How did you space the lights? I read your original post once more, you have 16 3 gallon pots, so I'm assuming 16 plants, what was their veg time and overall structure?
