If you haven't been spraying anything onto the leaves, I would say that's the early onset of powdery mildew.

id be more concerned with the leaves at the bottom. xD to me though it looks like calcified water or foliar spray... as for the bottom leaves, you might have some thrips or other hungry bugs..

Stem rot/Botrytis
How would you deal with stem rot at very initial stages? We dusted with cinnamon, sprayed with H2o2, scraped the affected area, wiped dry and coated with candle wax to seal the wound. Check this week's recent diary photos for more details on how it looks atm.

Should I defoliate during flowering outdoors?
(Autoflower) Should I defoliate? I made the rookie mistake of doing NO defoliating or lst during vegging, cuz they were skinny then. Did minor defol during flowering.It’s in full flower with 2-3 weeks left and we have about 7 straight days of rain. Worried about wpm and bud rot.

Mold on coco surface after top dressing
HELP! My plants are in week 4 of flower and I gave them an organic top dressing about 4 days ago. The entire top of the coco is now covered in white/grey mold! I tried hydrogen peroxide yesterday but it just grew back stronger overnight. Will this spread to the buds???

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?
Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Should I throw a net on her to limit her height or continue LST and leaf tucking? I’m siding with the latter but maybe it will help her in flowering as well if I spread her canopy under a net? Week 5 and showing pre flowering.

Humidity Spike - Bud Rot
Today I went in my tent and the dehumidifier was full and shut off and my exhaust fan broke. Humidity was at 90% for likely 12hrs. Buds were sagging. Back to 40% now and exhaust running. Should I be worried about bud rot?

Is this Soil Mold Safe?
After rainfall, I notice mold on top layer of soil. Approximately 70 days from seed. Photoperiod, outdoor grow in 7G fabric pots. I know powdery mildew and botrytis is a death sentence for plants in flower, but with these girls in veg - is it okay? What should I do?

Mold/fungi or am I paranoid
I have never seen all these white strands when looking at the trichomes so I was just wondering if this could be any time of mold of fungus? It doesn’t seem like it when looking at it but I have never had buds this dense and close together so just wanted to be safe.

Infected Leaves. To remove part of the leaf or whole leaf?
I had had pests and disease issues my second grow of Autoflowers. I believe it was hemp russet mites which spread disease on parts of many of my leaves. Would it be alright to remove only the part of the leaf that was infected or to remove the entire leaf?

Pollen sacks or powdery mildew?
I noticed what I thought was powdery mildew on a leaf, then noticed funny looking things right next to the powder. I think these are pollen sacks, and if they are I want to know if anything is recoverable, or if I need to scrap the whole plant/grow. "Second Grow" on my profile
