I think maybe mainharvest(?) has a lot more experience burning than I do. Hope he will chime in 
"I"..burn w/ lights off, and for 30 minutes or so. Then allow the lights to remain off for a few hours. It does, will leave a slight residue on your budding plants, which "might" reflect in the flavor at harvest.
I have only burned "prior" to onset of 12/12.

All you have to do is mix half cup peroxide 3% with two quarts water and treat leaves until gone with spray bottle..... problem solved. Peroxide is a must in any garden for watering as well it releases oxygen to the roots but be careful what percentage peroxide you use whether its 3% or 35% get the chart for mixing at gardeningwithhydrogenperoxide.com

A temporary fix at best, spraying PM can easily add to the issue, if you have it a sulphur burner is the best fix. IMO

it wont affect the taste if you dont use it after week 3 or 4 of flowering imo.

if your 3-4 weeks into flower than you have 4-5 week until harvest, you can burn if your 3-4 weeks into flower.

most if not all strains need a minimum of 8 weeks to flower many need more than 8 weeks.
if your going to do a burn do it no later than week 4 of flower and then harvest when they are ready, if you burn by week 4 than you will have atleast 4-5 weeks of flower after the burn and you will not taste the sulphur at all.

Don't Spray the buds!,, If it is only a few leaves then just pick them off! Get a Fan in your grow room and some Fresh Dry Air Blowing. Keep the Humidity Down, Don't over water or let any water stand. Potasium-bicarbonate is best but I just Sodium-bicarbonate (baking Soda) with water Not Too Much works! only spray leaves and not your buds, If it is on your top leaves then you have a Grow room problem, that needs to fixed fast! AIR flow and Ventalation is key!! Good Luck and Yes that stuff is Bad get it under control now.

Some good info on this thread
I have some tips as well
Almost everything mentioned here will help you 'control' PM...The suggestions for controlling in the later stages (Peroxide, Baking Soda) all good, just not directly on your buds. Keep culling affected leaves and spot treating until you get through flower, that's about all you can ethically do. Don't be a ********* and treat your buds with chemicals and give them to other people to smoke...
When I've had to deal with PM in the past, this is what works for me.
1. Finish your current flower run...try to save what you can by using the leaf culling method and spot treatment. You can even use greencure up through flower, just NOT ON YOUR BUDS...stem and leaf only.
2. Scrub your room....and I mean scrub...bleach wash your walls and all surfaces in your room. Make it Surgically clean. Cleanliness is next to Godliness...LOL
Here's where I might take some criticism....I'm a new guy here...second post and all and I have a difference of opinion on the use of sulfur burners, etc. They all work to control PM...which means...you will ALWAYS be controlling PM. I did the same thing, for almost two years...cleaned, burned sulfur, sprayed greencure and other hydro shop PM remedies, all the organic methods, etc. They all work fine for 'control'.
Ok - moving on
3. Get your environment under control. If you do NOT want issues in your grow room, you need to make the room a 'real' grow room and spend the cash to buy the items needed to control your environment. Dehum, A/C, Ventilation, Circulation are all critical to maintaining an optimum grow environment. If you can't control this, you will always be fighting something and not growing to your potential.
4. Clean your room....yeah, I said it...but it warrants saying it again. Your grow room should be kept clean, not like a teenagers bedroom
5. Use a systemic product for treatment. You can use Eagle 20, I prefer Immunox, made by Spectricide. It contains the same active ingredient as Eagle 20 (myclobutanil) and costs less (about 13$). Treat your plants with the recommended dosage.
6. Clean your room
That's it...your done. No continued burning of sulfur, treating with Greencure or whatever PM spray floats your boat. This is a one time deal. I live in the Santa Barbara, CA. area and PM runs rampant...and it did in my room until I did the above. I have not seen it since from my plants, It was coming out in cuts, cuts of those cuts, etc...I've been running a couple of strains for over 9 years now and those treasured mom's had it. It has not come back in those either. I've completed over 6 runs since I used it and it has not been back...period.
I know everyone tells you there is no cure, your stuck with it once it's systemic. Well, Immunox is systemic with a half-life of 24 days. It will kill the PM systemically and it will NOT come back unless you bring something in or have not...cleaned your room like momma told you..lol.
I hope this helps some people...a friend of mine from the NorCal area told me about Immunox after watching me struggle on another board with PM for quite some time. I'm glad he did.
Finally...don't use it in flower...duh..lol. You can use up to the flip, maybe week 1 or 2 but I wouldn't go beyond that.

:rofl: @ 3-4 weeks in, you are a LOOONG way from harvest.
*I* have done a burn a little over 2 weeks from harvest with no bad taste, but that is still closer than I would like to be.
One member here did a burn 1 week from chop and reported no bad taste, but that's really cutting it close.
But, with PM/Mold, you do what you have to do, or risk losing everything, or having un smokeable bud.
If you have a burner, use it, and use it soon.
Wet
There is a product out called PM WASH, makers of MIGHTY WASH. Use PM WASH first, really rinsing your plants. Then use MIGHTY WASH to rinse off any residual residue. MIGHTY WASH can be used even the day of harvest (sounds crazy, right?) and boasts it right on the bottle. It leaves no residue behind in your product. Smells decent too.
Obviously, rinsing your plants will raise the humidity level, so temps will have to come up and fans more vigorious. make sure your plants dry in a relatively quick amount of time to avoid too much humidity for too long. I've used it, works great. I would advise spraying in the "morning" before light gets too intense (don't want to burn your leaves...) or on an overcast day. (obviously I'm speaking of outdoor crops, indoors use your best judgement) A little spendy, but cheaper than loosing your whole crop.
