Pruning bud rot?

I sprayed with BT and Spinosad up to week 5/6 of flowering in my outdoor garden and now have noticed a few smaller colas got bud rot a few inches down from the tip. I pruned the effected areas off and then some, and am now wondering if it’s safe to harvest in a week and dry and cure.

I have read that it is systemic, and affects the whole plant, but I don’t understand that. I have also read some say they prune the area and carry on. I’m not sure what to believe.

I checked the larger colas and other areas of the colas inflicted with rot and there are no signs of it. I check daily on my plants and noticed when an area was light green, with white mold on inside. Only one area had mold that was grey.

Please let me know what you guys think. My gut says to keep an eye on it, it hasn’t progressed in the past week. It is for personal use as well.

Ps - two plants will be ready in a week or less and only one had three colas affected. The sour bubble had one small cola with a 2” patch get pruned, and has 2 or 3 weeks left on it to harvest.

Pps- all of the plants consume much less water than they used to, but I’m attributing this to the end of flowering.

Not sure why they are consuming less water. I'm a week away from harvest and their thirst hasn't slowed down. Still every three days. Been using pH balanced water and that is for the past two waterings

Ok , I was watering every other day. Every three now is about right for them.

What do you think of my mold issue though? If I can’t visibly see any mold, am I okay? I mean, there were only certain parts that got wet which got mold, 90 percent of plant did not receive the soaking and thus I haven’t been able to see mold. I’m mostly concerned if this is a systemic fungus that will be in all the veins and flowers no matter what.

I just cut off the infected bud. Seems to work for me. I think if you missed any the mold would grow big enough to see in a few days.

It is systemic BUT it only grows in areas that can support it . Like mushrooms the mycoplasma will not form without proper conditions. Just cut out affected areas and dry at a low humidity if possible.

Great, thank you for the sources. Makes me feel a little better about it. Do you know of something systemic I can use in early Flower to ward off mold later? I am already using fans, and will avoid foliars so late in Flower again.
This is only my fifth season, and am still developing a yearly treatment plan. At least I managed to avoid caterpillars this year.

There are methods you can use to prevent it. Some argue with me over it but oh well..
Never lost a crop to rot. Just spots of it here and there where buds were touching.
The method to my madness is to start with actinovate very early in veg. So when you transplant outside then start spraying. You can use right up to the end.
Second is I wont foliar feed anything that is "food"
In order for a plant to absorb feedings with foliar the ph has to be acidic (and acidic ph is what promotes things like PM and rot)
I will spray and root drench silica because of the high ph and because it is beneficial.
This next yr I will be using cal carb to spray as well... because of the high ph and because it will bring extra Co2 to the outdoor plants.

When you do get rot you can cut it out of the plant if you catch it early enough and spray a peroxide water mix.

You can also do a layered harvest where you take the fattest buds first then wait for the smaller ones to beef up.

Rot needs a wet cold acidic enviroment to grow...so I do my best to keep the ph as high as possible
