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

OMG...I'd have put a note on the fixture that said "DO NOT F'KIN' TOUCH!"
I told them that, just as you worded it too. And when they would do it again they would have some excuse on why they needed the light for just a minute and then forgot to turn it off.....even though I told them they couldn't even turn it on for a minute.

Light is an interesting thing with flowering. I've been told almost since I started smoking that absolutely no light during dark hours. I've found this to be untrue. Naturally they do get light during dark hours. Flood light definitely going to cause issues left on. Few minutes really shouldn't be an issue. Indirect light isn't a terrible thing.

I made the comment about not even being on for a minute because I was trying to make a point about the importance of the light being off. @Sativa1970 Explained it best to me a while ago. A light bright enough that you can barely read a newspaper if left on all the time so the plants can adjust will be okay. And I am sure an occasional flash of light would be harmless. If not, no outside plants would ever make it to harvest. I recently read about someone causing their outdoor plant to reveg from a bedroom light being on too much.
 
And with the sun out today and the wind not blowing I found several leaves infected with septoria. Those leaves were plucked within a couple of minutes from one plant. And I got more off of that plant after this pic. I wanted to show you so you didn't think I was crazy.

The branch I showed you guys a pic of yesterday that I thought the leaves were drooping due to septoria and you guys said it was due to deficiency issues. You were right, it was deficient because it was dying. Today all the leaves were wilted and I realized the buds on that branch had not grown any compared to the rest of the plant so I cut off that branch today in hopes it will allow what remains of that plant to thrive.

Yes. Plants work a lot like we do. Up with the sun, down with it promoting health. I've got a strip under the closet door my flowering experiment is at, light that gets through doesn't seriously do much. I assume the little bit acts a bit like moonlight.
Frustration with outdoor lights. Last year I was back and forth with my dad trying to get him to turn off the hps he has with the outside garage.
 
Without getting too technical, there are two hormones that determine veg (A) or flower (F). One is produced as the leaf turns light into glucose promoting veg(A). The second is flowering(F) and produced when the leaf is preparing glucose to be shipped out of the leaf. Both are produced through the life of the plant. The daily light interval DLI determines how much (A) is produced. Hormone (F) is produced 24/7 but slightly increases when the leaf is not currently focusing on photosynthesis. When there is more hormone F than hormone A it triggers flower. Adding ambient light from dusk to dawn will increase the total DLI. You will need the days to get even shorter with ambient light for the DLI to get low enough to tip the hormone scale. Flowering with shorter days means less glucose to build flower.

Leaves are at peak production at first full light. Hitting them with a short, intense, sudden light at night will send a flood of hormone A into the plant. This is enough to keep greenhouse plants in veg all winter. Flowering plants can be slowed or hermi from the hormone shift.

So constant ambient light greater than a harvest moon is not good for glucose. Switching the spot light off and on is definitely bad for hormone balance. We want the hormone balance of a supper model. Not a female Russian shot putter.

I like how you explained it. I don't know much about the science of it. In the recent months I've just learned how much more important ppe, ppf, nm are versus lumens and kelvins. I don't quite understand it all but I do understand the gist. Always being told high lumens and specific kelvins, what I'm coming to find out is the par and other measurements are far more important to pay attention to.

On the surface they look almost interchangeable. The details in the measurements make all the difference. PAR is how much useful light hitting the leaf and DLI is total PAR per day. Those two are the base fundamentals to understand and apply first.
 
I'm definitely still learning. I imagine ten years from now I'll still be just learning things. Outside I'm knocking trees down for more daylight. Inside I started with extremely basic grow lights and finally I'm working with a couple of lights that actually have deeper IR and even getting up to 1500 ppf, 3.1 umol. Very slowly retaining the information on what everything is doing.

I think my dad said it best......."who knew there was so much involved in getting a weed to grow"!
 
I was wondering if anyone here has dealt with Septoria firsthand. I never really thought about it until the other day but now that I am thinking about it, I am curious why my plants never get the dappled, yellow spots I see in every article I have read about septoria. It makes me wonder if maybe I have a different fungal issue instead. I have 3 different strains growing outside or I would just chalk it up to the strain I have. And I guess it isn't a big deal.....the treatment would be the same for any fungal infection......I am just curious.
 
I have a new problem that is a direct result of my plucking leaves yesterday. I decided to start a new thread but thought some of you might want to follow what is going.

 
Some of my plants may not be as close to harvest as you think. Other people who have grown outside in VA say harvest is between mid- and late October.
True but those same plants are closer to harvest than you might realize. While the lights coming on might have kept some of them from being 100% dedicated to flower development the clock is still ticking as they say. Come mid to late October and the days are getting even shorter. If the lights do not come on ever again there just is not enough time left for the plants to make up for the lost sunlight. Add in the cooler nights and the possibility of frost.

Cold nights and frost will not kill the plants but it will take more time once the sun comes up to re-warm everything back up to growing temperatures. I have grown several plants through a Michigan autumn and watched what they do after a frosty night and how they handled snow. The plant just slows down and the buds stop growing larger. There is some increase in buds feeling denser but the increase in size just about stops.

It was a worthwhile experiment. I have left plants out later in the season since then but now that I know that frost and light snow will not kill them it is not worth the effort to continue the experiment.

It is supposed to stop raining the day after tomorrow. Once it stops raining, I am going to spray the plants with this stuff I found called Crop Control by Trefecta and remove any mold I see. After that, if I see anymore mold all my plants are going to harvest no matter how done they are. I did flash dry a bud from the plant that received no light interference and I have had 2 people try it and they really liked it. I am afraid to try it myself because my asthma has been acting up and I am scared trying to take a hit of some harsh stuff is going to give me an asthma attack.
