leaf mold on seedlings...

[oakley]

Its been a great year for seed starting so far. No fungus gnats or aphids...my battle
last year that I've been prepared for.

Started seeing leaf mold spots. Much rain and humidity and warm weather this Spring.
After last years troubles I inspect all trays like a hawk and have some mold spots.

After searching, I think the best is potassium bicarbonate but can't find what I purchased
last year. Baking soda? Neem? Does baking soda and potassium need a carrier oil?

I did use peroxide with a bit of vinegar on a few spots.

All seedlings are outside under shade now and no rain in the forecast.

I've been running the fan high and bottom watering as always, and only when very dry
almost near limp. Dehumidifier 24/7. Some plants I potted up have been outside for
two weeks and I'm seeing some PM bloom. (powdery mildew)

Always something new to hit the babes.

Still looking for the potassium bicarbonate...I needed it last year for my summer squash
and rosemary but never had any problems for the first time in years....
