Yes, it is dissolved mineral salts that are left behind once the water evaporates.

I have a cool mist humidifier in my tent, using RO water. Two of my plants that are close to the humidifier have started to get leaves with rust colored spots and yellowing. The left two are fine. Any ideas? The only difference is the mist may have been spraying on the first two.Week 3

Deficiency ? Chlorine from tape water ?Spots appeared after last watering, 4 days ago. It doesn't seems to evolve to more spots.
Using basic gardening soil. Chlorine in tape water X 4 those days, because of covid-19. So if not a deficiency, might be Chlorine ? Or Chlorine killing life on the soil?

Should I cut the first leaves to maximize the growHello everyone
A friend told my that I should cut the first leaves of my plants (the first that came out from the plants, not the cotyledons)
What do you think about this idea ?
And can this really maximize the size of the future buds ?
Thank you for your responses ! :)Leaves. Other
