Powdery mildew advice much appreciated

GhostRR · Apr 13, 2025

Hi.

Was going to flip to flower but noticed some powdery mildew on edges of some leaves.

I have earth's ally 3 In 1.

I'm looking for advice. I definitely need to work on fungus and pest management. Been lucky with no bugs but have pm sometimes. I use this 3 in 1 a while ago and seemed to help.

Just wondering if there better ideas?

Also, since she is in a tent with other small ones I think I need to spray those also. Or are they too small to soak with the 3 in 1? I believe you have to spray until run off of leaves. Worried it might hurt a small plant...

I don’t see any pm in your pictures, but the best ipm for pm in veg and early flower is sulfur. Spray every three days up to date 24ish if you’re worried about it showing up late.

It's just beginning and need close up pics to see. Kind of like through my loop. Hard to see now but I'm worried it will spread

Earth's Ally is fine for all your plants but never spray anything while the lights are on. I've used it and still have a bit left but changed over to neem as it helps control bugs and PM.

What type of sulfur (powder, liquid or smoke) and how do you apply?

What kind of neem? A foliar spray?
Amy recommendations?

I used the 3 in 1 once when lights were on and it ruined a few small plants but they recovered eventually. Hence my hesitation.

But maybe I messed up my spraying with lights on in morning

If it’s a small area definitely cut out the affected areas.

Silver bullet works really well and doesn’t clog your sprayer. It’s a powder you mix and spray. If you’re always spraying in veg and early flower you should be able to eliminate the pm. Reapplying is essential as just a spray or two pm will go away ur comes back. Pm roots its self to the leaf and stems. That’s why it comes back if you don’t keep reapplying until it’s gone for good.
And just a heads up to anyone wanting to use sulfur, never spray oil products after sulfur. You can rinse the sulfur and then apply oil based products.

Maybe do some defoliation on that one plant on the inside to get some better airflow through it and it’ll be a little less spray you need to use

Good idea.
I'm about to chop in my flower tent so I'll have room finally to put her in her own 2x2. Then I'll defoliate and spray with neem oil concentrate I just bought (diluted obv) .

How long can I use 3 in 1 and or neem spray in flower?

Beazy · Apr 14, 2025

That I’m not sure of I don’t spray anything once flowers start but that’s just me.

GhostRR · Apr 14, 2025

Yea that's the obvious answer.
I hope I don't have a problem.

I've only had a few harvested plants and the one finishing now actually has a tiny bit of pm but doesn't appear to be in the buds.

The buds are pretty dense and Solid and I'm very happy about that bc I wasn't able to get dense buds on other harvests.

But then again that's an extra layer of worry as thicker buds hold more moisture..

I've used several different types and recently switched to this

I have to add dish soap but no biggie and I never spray anything while lights are full. I'm in a greenhouse with LED's so for me that means dawn or dusk I can spray.

I've sprayed up to a few days before harvest and I always spray down the plants with water the day before harvest just to wash off the dirt and I've never smelled or tasted any neem.

I have to move the plants outside to flower and it's a battle out there between the aphids, spider mites and moth larvae. If I don't use anything I'll lose most of the tops to moth larvae and an aphid outbreak will severely weaken a plant.

not seeing any obvious sign of pm on the veg or flowering plants

chance your overreacting are high to me ...

pm will usually spread fast enough to notice some larger spot on the leaves when it happen.

what's your seeing through your loop might just be non glandular trichrome that more or less cover the plant.

and i m really not a fan of treating the plant when that's not needed ...

This seems like the most probable answer...

Could also be the water from dehumidifier I was thinking... I use tap water although I have it sitting in air stone too get oxygen and release chlorine.
