Please help to recognize the problem

Hi, this is my plant, that's around couple weeks old, and it has some lighter green patches and deformities. What can cause such problems?

did you water on it at all. Looks like some nuted water or something splattered on them. But that's just me...

As he said how do you water them with nutes. Do you pour it over the plant or close to the soil without touching the leaves with the water?

No, nutes are yet to be introduced.

Whats the pH of the water you are giving?

Have you been giving water with irregular pH levels?

I'm watering her with the same water i used in previous cycles, and it was ok then.

Looks like water on the leaves magnified the light and partially bleached the leaves. No biggie.

Slight case of nute-burn via watering with nute water. It is impossible to not to splash leaves if using nute water. I keep a spray bottle of regular water near the plants and spray the leaves after using nute water. Works for me.

Good luck, BigSteve.

Its a huge debate about what causes this mozaic pattern on the leaves. Some will say its a mozaic virus, but there is no proven fact that cannabis can even get any mozaic viruses. Still new findings and tests being done on what causes this. It will not harm your plant threw its entire cycle having a few mozaic leaves. I doesnt hinder growth or buds.

what is your soil type? I had similiar issues with MG potting mix with it being overfert issues. light green and in few days itll yellow out and die.
