White Spots On Parsley Leaves

(Almaty, Kazakshtan, Central Asia )
I have grown the Parsley from seeds. I bought the soil, but as I live in Central Asia, there is never a guarantee about the quality of the product that you get here...and everything is in Russian, so I don't even know what type of soil it is. The plant is indoors and receives lots of sunlight.
It has tiny white specks on the upper side of the leave, but nothing underneath. So could someone please help me identify this and what would be the treatment?
So glad someone from so far away from where I live in the United States views our website.
Let's start off by eliminating a couple of things.
First, I don't think your problem has anything to do with the soil you are using. In my opinion, if it did, your Parsley wouldn't be growing so well. Your photo (thanks for submitting, by the way), shows a well-growing herb.
Also, the amount of sunlight it receives shouldn't be causing white spots on the leaves.
The two things that could cause white spots, are insects or a fungus. If it's a fungus, you'll need to treat the plant with a fungicide made for edibles. If that's what it is, it should disappear in a few days to a week if you follow the instructions on the label.
Secondly, it might be insects. Aphids or spider mites can make white spots on leaves. Look for whitish webbing as a sign of spider mites. But, also caterpillars can do this as well. Do the white spots turn into holes? If they do, than it's definitely insects (most likely the caterpillar). Literally, turn over leaves and look for caterpillars. An insecticidal soap would be your best bet for this problem. Use the soap, and the insects should be a thing of the past.
Just don't ignore the situation. They are a common thing for Parsley, but if it is a fungus or an insect, either way, you have to get rid of them or the plant will become unusable.

Hope this helps and please let us know how it turns out!!
