Need help! Crust on leaves

[Happypaphy7]

True if they are the red mites. But not if they are the two-spotted type. Strong magnifying glass will show either.

True. It only applies if it's red spider mites, which I actually don't need to do this because they are about the biggest pest mites I can see with naked eyes.

It's those super duper little guys that are almost invisible that pose real problem.

Use a formula/solution with alcohol in it. Most mites don't like humidity also.

Some do, some don't.

Red spider mites are typical ones that thrive under hot and dry conditions.

This is my observation:
the damages or patterns on the leaves are mirror images , that means whatever happened to cause the pattern started when the leaves were still in the young stage (both sides of the leaf still facing each other, not fully open )

My initial thoughts also.
I didn't think it looked like typical mites damage.

Wendy.

Is there a particular brand of horticultural oil you prefer?

Can you spray the hort oil onto buds without damaging them?

Thanks,


Duncan

It's Green Earth Horticultural Oil concentrate. You can get it at most plant places....I got mine in the plant section at Canadian Tire. I don't recall ever spraying flowers or buds. I do give the entire plant a coat, both top and bottom of leaves. I try to do it at least once a month....growing indoors is dry and mites love dry.
