I recently repotted some of my plants. the leaves are turning yellow with black spots. Is this a fungus?
The potting medium consisted of perlite, oildry, and plain potting soil.
I'm thinking the potting soil could have had some fungus in it.
So I sprayed the plants with a water, hydrogen peroxide, and veg oil mixture. Is this good enough or do I need to drench the pots with a water and hydrogen peroxide mixture that would act like a systematic?

I also lowered the ph of my water to 6.3 - 6.5 could that cause a problem?
When the past is forgotten it is destined to be repeated.

Sounds like a fungus to me. As to how to treat it, I'd imagine it would depend on which fungus. Hopefully someone else will chime in.

Adam,
Sounds like you are on top of this. What temps do you have them in. Watch drafts.

I'm surprised a typical fungus could thrive in such a pH....can you give an update, Adam?

By spraying the plants with a water, hydrogen peroxide, and veg oil mixture.

Also I picked off and discarded all affected leaves.
