What would you say those little white spots are? Outdoor grow.
I find it interesting because they've appeared on plants that are two months old and others that are just 15 days.
Hi Buddy. The white dots are usually caused by the sun through little water droplets, like a magnifying glass.
You might have had a rain shower and the sun came out shortly after and shone on the leaves
If you water the plants don't get any water on the leaves in the sun. You'll get the same marks.
