PM issue and did Sulphur burn but still see PM

Here's the details......In week 4 of flowering. 8x8x7 tent. Shut off ALL fans (fan blowing in, exhaust, and circulation fan). Filled sulphur burner about 1/2 way. Started the burner 4 hours after lights shut off. Burned for 4 hours. Temp didn't get higher than 80.4. Humidity reached 81. After the 4 hours, I turned all the fans back on. It remained dark for the next 4 hours before the lights came back on.

I still SEE the PM on the fan leaves. Is it supposed to disappear?

If it is supposed to disappear, how long should I wait to burn again? All the research I found said wait at least 3 days.

Should I burn for a longer period of time? I found a few articles that said if you already have PM, burn for 8 hours.

Should I try wetting the plants before turn the sulphur burning on first? I've read that it will make the sulphur stick to the leaves better.

Should I go ahead and trim off all the infected leaves as well?

And PLEASE, I would like responses from people who HAVE experience with sulphur burners. I don't need info about what sprays to use cuz I have used them before and it doesn't get the job done. That is why I am using the burner. Thanks!

i know u tried all the sprays, but if u realy dont want pm use eagle 20. youll never see it again.100 % for sure.

Can't get it in Cali. Closest thing we have is GreenCure but I wanted to try the sulphur burner first cuz I was told and researched that it is better. Plus if I use the GreenCure first, I wouldn't be able to try the sulphur burner cuz you have to wait 30 days after using the an oil based spray.

I've heard too many negative things about it already.

yes u can. i live in cali. its every where now. used to be hard to find, but not any more.

I use the sulpher to prevent PM and growroom diseases. I burn it everyday from veg to to 4thweek. Before the lights turn on.
Once you have it your fucked. its in the plant not and when its on the leafs in be in the plant for a week. Try to keep your humidity under 60 at all times. Chop down as quik as you can before its gets on the buds.

Sulfer burn 4 hrs. each day for 3-4 Day's in row. Remove all infected leaves!!! And you can get powder form sulphur add to water in squirt bottle, sprayer, and spray that directly on plant. As well as burn. Keep humidty in check (lower) & fans (airflow) And watch them like hawks! PM Sucks sorry to hear u r having to deal with that shit. I hope u conquer the crap. And Yes... as mentioned above ...Eagle 20 kills it...but u r 4 weeks flower might not want that on buds, just when in veg. Peace

Yeah I'm not happy cuz my temp has never gone over 81 and the humidity has gone no higher than 62 1 time. Its usually between 48-56%. I have 3 fans blowing on the plants. I trim all the big fans leaves almost every day.

This isn't my first grow but its the first time I've gotten PM and I'm not sure how or why cuz my conditions seem fine as always.

Anyone else that can help?

I know this an old thread, however I must comment for anyone who stumbles across this via search.

Eagle 20 is a powerful systemic fungicide that is made from ingredients that are KNOWN CARCINOGENS. Its intended use is for ornamental plants only. Look up the MSDS, the second ingredient is a known carcinogen, and the first ingredient is a suspected carcinogen. Please do not use this stuff on consumable crops.
