Is this leaf septoria? If so, what should I do?

I was definitely curious about that. I thankfully caught issues before they could get that far. I won't let a plant get that far again lol. Half a plant basically disappeared last year. Alcohol might be able to be a solution for mold and bacteria. I've went that route experimenting and got good results. Last bit got grainy. Little bit of a waste of alcohol. 😅

I have the mold issue and making live rosin. Wouldn't the heat press separate the good from the bad?

It isn't the heat as much as time. 180deg for 3 hours will kill most all types of mold and spores. Some, not all release mycotoxins as a defense mechanism. When dry conditions threaten survival, some molds release toxin then spore. Mycotoxins can survive 500F for over an hour.

Most all mold spores are 2 to 40 microns. Hash screens going down to 45 microns would leave the spores in the bucket. 25 micron bag would catch some spores. Place hash in 200F oven for 3 hours to decarb and kill any spores that slipped through if you went down to 25 micron. You can safely smoke or eat it at this point.
 
I cut off four smaller branches Thursday night and started harvesting. Then I realized not all my buds are as ready as the one I flashed dried the other day. Yesterday, I started going through and removing all large and medium fan leaves and any leaves that were not 100% healthy, including any leaves with septoria, damage from deficiencies, and bug damage. I also removed anything that was not a healthy shade of green, which I noticed a lot of the bracts were starting to turn brown. I don't know if this is normal or not. I also removed any remaining leaf stems from where I didn't remove the stem all the way to the branch. I removed any mold I came across (I didn't find nearly as much as I thought I was going to). When removing mold I removed anything within 2 inches from where the mold was and tied a plant ribbon there so I could better keep track and monitor these areas. My kid has been home with strep and I have 100 things to tend to right now so I have had a hard time trying to get this task done. I don't have time to finish it today so I am going to put my dad on plant duty.

I have done hours of research when it comes to pruning during flower. Everyone has something different to say. Some say don't do it at all, some say light pruning is okay, some say it is okay until a certain point. I came across one video on youtube from the Illinois Grower's Club that says to do a heavy pruning week 7 and remove all the large fan leaves. They say at this point the plant doesn't need them because it is about done with bud building. They say removing the large fan leaves will stress the plant, which in return will cause it to produce more trichomes as a defense mechanism. I guess I am getting ready to find out if they are right.

I think I need to proof read before posting. I don't have 😅🤣. Just trying to figure out safe ways to handle. I'm sure I'll run into a plant or two over the years. Though if I get a good rotation going losing a plant isn't going to be a problem.

Nature does it's own thing. Just because one thing does as advertised on one plant doesn't mean it will on another. A lot of trial and error. Pruning.. this year I trimmed according to growth and damage. My OG Kush is going back into veg after taking everything off besides a few leaves. How much damage is took this year it should be dead. I'm not sure if stressing alone will produce more trichromes, needs to be dry as well. Combination of a lot of little things is needed.
 
Low humidity and/or good air flow over the leaves will prevent mold issues. I learned the hard way early on, always pick an outdoor location that funnels a good air flow. Indoors I use a lot of fans.

Recently realized I lost a plant. Forgot I had hung it to dry in a storage rom back in July because the drying room was full. Teenaged me would have been upset abought loosing a lb of bud. Now I just thought it was funny. Hunting gear hiding behind the bush.

I think the safest way is to dispose of anything that is infected with mold or has come into close contact with it. Especially if you're not the only one going to be consuming the fruits of your labor. Some people, like myself do not do well with mold exposure. Because of the season change and all the moisture, mold and decay in the air I cannot even be outside for more than 30 minutes before I am wheezing.

Trust me, I know it hurts to throw away bud (unless your @Sativa1970 ! ). I had this beautiful bud yesterday that if I hadn't thrown it away due to mold I probably would have entered it into the bud of the month contest. It is not worth trying to save an infected bud and risking your or someone else's health, but you risk infecting more of your crop. And that will hurt a lot worse than tossing a bud.

I never paid attention to it until I started growing but it seems like we almost always have at least a slight breeze going. If I could drive a straight-line east I would hit the coastline in probably 30 minutes, maybe not even that long. I don't know if being that close to the coast gives us a constant breeze or by dumb luck I picked a breezy spot because that was not one of the things I was choosing a spot for my plants, however, they seem to always be moving.

Are you talking about a plant this close to harvest or generally in flower? Pulling all the fans within a week of harvest to make trimming easier is kind of standard operating procedure around here and is too late to have any big effect on the flowers.

There are as many other types of thinning in flower as there are growers, so you'll discover what's best for you as you grow more plants.

Both. I think the rule I am going to apply to future outdoor grows is if it is showing signs of not being healthy then I am taking it off before it has a chance to decay. It seems like the mold spots I found came from when I didn't pluck the leaf stems all the way off to the branch, dying bracts or unhealthy foliage.

I was thinking about mixing water and H2O2 in a pump sprayer and spraying my plants. Any thoughts on doing this?

I used straight H2O2 at 3%. It coverts to water really quickly.
 
You can spray root to bud with hydrogen peroxide without harming the plant. Stay at 3%. Lower will not kill the mold and higher may harm the plant cells. It will not stop reinfection if still in the air. Wet buds and leaves are prime real estate for fungal growth. So right before harvest or dry the plant after. It will not remove any toxins already in the bud from the mold.

You said you sprayed it on the bare stalk. I was thinking about spraying the entire plant, buds and all. Does that change your thoughts on the subject?

What Sativa said, but why? If you have a plant covered in botrytis you should bin it. If not, spot treating the areas after you cut out the rot is better. You would need to dunk the plant in a bucket of hydrogen peroxide to ensure it gets into every crevice.

Additionally, the scientific evidence that 3% concentrations of H2O2 kills botrytis spores is not there (even though I've done it):

Spores of Botrytis cinerea can germinate in the presence of up to 180 mM hydrogen peroxide and its mycelium can develop in the presence of even higher concentrations.

Evidence for rapid breakdown of hydrogen peroxide by Botrytis cinerea

Abstract. Spores of Botrytis cinerea can germinate in the presence of up to 180 mM hydrogen peroxide and its mycelium can develop in the presence of even h
academic.oup.com

3% H2O2 is around 34mM, so 180mM would need to be over 5x stronger. I don't know that anyone has tested the effect of high concentration hydrogen peroxide on either trichomes or terpenes, nor is it safe to use casually.

My recommendation is to find and cut out the rot and monitor the harvest well during drying and curing. Getting the harvest down to the low 60% range as quickly as possible after chop should increase the chance of success.
 
I think you have focused on saving these plants too much. I admire your determination to care for these plants and all the problems you have overcome in the grow. You need to switch from trying to save everything to a more discerning view. You need to carefully look through the buds with an attitude of, if in doubt, throw it out. Would you spray H2O2 on a moldy strawberry then eat it? Of course not, because it wouldn't remove or kill the mold inside or remove any toxins.

If you didn't already have health issues or if this was your only plant I would understand the desire to take some risks. Even if you only get 2 or 3 Oz of good clean bud out of a 6 Oz plant, how many plants do you have outside?? Four or five? That is still a half pound. How many do you have growing and drying inside? It is time to focus on the healthy and abandon the sick.

If you only keep the 100% safe bud you will still have enough smoke to hold you until next harvest. The next generation is already growing. The knowledge you have gained having dealt with most every grow issue but still have enough to smoke until next harvest should be considered an absolute win.

I have been tossing everything questionable and anything around it. The problem is we are not talking about ounces of weed.....we are talking pounds of it, and it is taking me a very long time to get it done. I was considering spraying with H2O2 to kill any mold spores that might be there but cannot be seen yet and have not begun to cause issues and to help prevent the spread of the mold until I can get to the removal of the it. This has been a huge undertaken. I have 5 plants outside. I have been trying to get this done for days now. I just checked a daylight calendar and today we only have 11 hours and 31 minutes of daylight and each day there is a little less daylight than the day before. During those hours I have a lot of other things I have to attend to too. I was actually wondering if I could get away with wearing one of those LED headlight-headbands so I can work on this project during the night hours. That would be the best for me so there wouldn't be so many interruptions, but I didn't know if that would cause the plants to hermi or reveg. Here are pics from today so you can see what I am dealing with.

This is before I started stripping away the fan leaves.

I am almost done with this plant. I measured it and from the top of the soil in the planter to the top of the highest cola is measured 60 inches tall.

If they're all ready to harvest and you have time at night, just turn the floodlights on and work at night. Nothing bad will happen within the next week if they're all coming down. It takes longer than that for a plant to respond to changes in light schedule.

And even if they hermie at this stage it doesn't make any difference to the harvest.
