Hello guys 
First-time posting and first-time grower here in need of some advice and active feedback on these 3 beautiful queens!
I have noticed these spots on a couple of leaves a couple of days ago and I kept an eye on them to see if they would spread/enlarge or get worse and after three days, the spots look more or less the same.
Plant 1:
The other 2 plants have the same spots but a lot less
Plant 2:
Plant 3
Hopefully, these additional details might be helpful:

Nothing to worry about. Could be a little hot spot from nutrient. Leaves bunched up together when they were beginning to form at the nodes will indent each other. Looking good!

Looks like nothing to worry about could be a flight potassium defiency causing the spots they don’t seem to be getting worse are they?

A little update on how is it going… @Dclark intuition was right and I should’ve checked better for pests because in the past 4 days I have noticed these little monsters ( Thrips) wandering around the leaves and steam; I must say they are not many (or at least this is what I’ve seen with the magnifying glass). I applied some water and “neem oil” 2 days ago and I will keep an eye to see the development of this.
As usual, any advice is much appreciated!

As an overall development, I think is not bad how big their grown, of course, all of them have different sizes but we are the beginning of 6th week today.
