A few tiny little holes in some leaves

What is causing this? Something is causing tiny little holes in only a few leaves on some of my 4 Durban Poison plants.
These are photo period Durban Poisons in 3 gallon pots(11 litres) and they are now 2 months old and about 24 inches (2 feet tall)
I move them outdoors in the morning to catch the sun and in the evening I move them back indoors. I have looked very closely and carefully and cannot see
any little bugs at all. What could this be? Also another question: Will the 3 gallon pots be fine to grow them in until harvest time? I am worried they might get root or pot bound. Or should they be fine in the 3 gallon pots? Thanks very much for your help and advice in advance.

Get a scope mites/tripes can be damn small.
3 gal is fine you might have to water more offten and the size of the plant will be limited by the avalible space of root growth but i would not be worried about negitive effects of root bind unless you plan to keep them in veg for several more months

We have a tiny green grasshopper, could be a juvenile, here in Southern Africa that leaves similar internal leaf blade damage just on a larger scale on outdoor plants.

I am in South Africa...Garden Route, Western Cape...and yes I know this tiny little green hopper but it's not one of those...this is something much much smaller...so small that with my jewelers loup I can detect F-All.

whatever it is it's so small that with my jewelers loup I can detect F-All. These are photo period dp's so they are known to have avery long veg period before they start flowering so they gonna be in these pots till harvest time which will be at at least May /June next year. (I am in South Africa)

I would up pot to the biggest pots that practically work for you and your situation. Take my thoughts with a pinch of salt, I grow in 250 ltr bags standing on pallets....

Those leafs look mostly green so its not a nute defficency, if not bugs then its wind damage or the like. If your gonna have another 3 months of veg i would put them in the ground or very large pots/beds 100+gallon

Could be wind burn or light burn when those leaves were sprouting, I’ve had this issue before on random leaves, and never saw pests, figured as long as it’s not happening to other leaves then I’m fine,
just monitor.

That is what I don't want to do if I can help it because then they are too heavy for me to move around. I specially picked the 3 gallon pots as they are the largest that I can still pick up and carry to different spots in my garden to keep them out of the strong coastal winds that blow here and also I can place them where they get the most sun during different times of the day and can even move them inside the house if needs be. Last year I had my plants in big heavy 10 gallon pots so they were stuck in one place and sustained lots of wind damage such as broken branches. It can really blow a storm here and often that's why it's such a popular place for kite surfers. No I know it's not a nute deficiency as my plants get very scientifically calculated feedings and water. They are extremely healthy it's just those tiny little holes but yes I have since read on other cannabis grow sites off this very same problem and your answer that it could be from the wind is one that is voiced on many other sites too as in all cases no insects however small have been detected. Just strange that it's only on average on 1 or 2 leaves per plant that the tiny holes appeared. So I have just cut those leaves off and will wait and see it it is going to happen again. Now I have also found quite a number of articles of growers who compete to see who can grow the biggest plant in the smallest pot and I was amazed to see what can be achieved but the secret is that what you feed your plant has to be very balanced and nutritious to compensate for the small amount of soil that it is growing in. Only other option if the 3 gallon pots really aren't the solution is building a greenhouse and I don't want to really go to those lengths.

I would stick with your 3 Gal pots, if that is the most convenient for your situation. I have taken a quick picture for all to see the green grass hopper and the damage she does, if you come near the plants they jump off, possibly a reason they go unnoticed. 1st pic is the little green grass hopper and the next pics are the internal leaf blade damage they leave behind.

Happy Growing

Hmmmm yes that does look like that could quite possibly be the little culprit then. Little bastards and I did find one of those a while back on one of my plants as i carried them back inside my house when it became dark. He didn't even jump of and I found him as I was inspecting my plants for invaders like I normally do. I then grabbed a can of Doom and just gave him a quick short burst and that was the end of him.

I live just outside Cape Town on the Atlantic seaboard, it can seriously blow here too. Wind can also cause splitting or tearing of the leaf blades but I doubt wind damage would be confined to 1 or 2 leaves on a plant. I also defoliate my plants a bit, to make them a little more aerodynamic to counter our winds here, as mine ain't moving from the cannabis garden till Harvest in May /June next year.

Hahah yip that's what I do too...make them a bit more aerodynamic to handle the wind better and also to allow more sunlight to penetrate. I am on the Garden Route about 350 km from Cape Town and right on the coast. About 500 metres from the sea itself. The wind pumps here this time of the year right through to around April next year...very popular with kitesurfers for that reason.
