?? Powdery Mildew ??

[brown_thumb]

I found a tiny spot on one leaf. I've researched 'powdery mildew' and this doesn't look quite the same, to me. I was thinking I might have dropped a bit of gypsum or DE on it but it's been raining every day so I assume it should have been washed away. I don't know...

I can't foliar spray for 2-3 days because it's still raining here.

Looks like you're growing a cocaine plant.

Either that or it's gypsum or DE. Doesn't look like PM to me. And trust me, I've cried more than my fair share of tears over the woes of powdery mildew in my garden.

Looks like a new whitefly colony to me.

Definitely not PM

Does not look like PM,

Maybe try snorting it.

Looks like bird shit to me. ;_)

Ha ha... maybe a bird ate cocaine and pooped it on the leaf.

I did another thorough check and that's the only spot. I must have dropped a bit of DE or gypsum on it.
