Should I prune older big fan leaves?

[Len Goodman]

Was ready to strip my plant over a few spots like these.

Try some uvb treatments it will kill all your fungus.

Those spots 'ain't nothin'' man you should see the real PM here in mid-Michigan. The wild phlox and every herb in the gardens that doesn't get full open air circulation is covered with it. It's unsightly and will mess up the leaves but these plants are over 20 years old and they just keep coming back and blooming every year. Bonide makes a pre-mixed H2O2 spray that works great too, if you can get it.

Welcome. Always great help around here sharing knowledge to us noobies.

 

[Mastajay]

Will do! Thanks again. Nice to know it's not the end of the world.

Trying milk today. Supposed to be a hot sunny day and the sun is supposed to work with the enzymes in the milk to kill mildew. Best case scenario I think!

I have a UVA/UVB reptile bulb. Will that work?

 

[Len Goodman]

Refer to my grow journal for day 8. Make sure the bulb is 3 % with the uva. If you look at my journal I have posted a lot of plant reactions. I don’t want you to burn your plant. Read what I did.

 

[Len Goodman]

You are out door too so it’s already been exposed. Just concentrate in oth fungus area.

I don’t know never tried it on fungus.

 

[Len Goodman]

I don’t know never tried it on fungus.

But it’s so suppose to kill it according to all science books even the bacteria in your soil so try not to get there Then get you some bacillus to give the good stuff back and bacillus fights bugs and fungus. Micro biology.

What’s PM

Powdery mildew

 

[RAIN MAN]

Cut off all the lower fan leaves. They will not get as much light as the rest of the plant, and you will get more growth toward the rest of the plant. They will just slow the plant down. Make sure all energy goes toward the buds.

That's good advice when the plant is in Veg, but I would avoid that in Flower

 

[InTheShed]

I'm with Blew (no surprise). In flower the plants will expend energy replacing the fans instead of building buds.

Also, outside plants get sunlight at many different angles so a lot more leaves get light than in a tent.

 

[Mastajay]

Yeah. Makes sense. I just adjusted the nutrient mix to higher phosphorus on Saturday so I will stop all defoliation at this point.

 

[FraidyMan]

I'd ask around here for a hydrogen peroxide mix for the mildew. You might not want to spray that on your buds because it is sulpher based and if you've ever smelled sulpher.....blech, rotten eggs smell. Safer is a good product, though. Maybe dilute it if you do use it. Those large fan leaves on the bottom will eventually shrivel up and drop off on their own once the plant has extracted all it needs from them. And welcome!

I had powdery mildew on some succulents, and one soaking with a mild solution of bicarbonate of soda (1 tablespoon in a quart) got rid of it in 3 days.
