What are those dots?

[Helmut79]

Those dots have appeared everywhere on my little plants (first picture).

Then I noticed exactly the same spots on the plants I was about to harvest (second picture).

I'm gonna say one thing for sure - these are not caused by any kind of bugs.

Is this some kind of deficiency? I'm feeding Canna Coco A&B as a main component and supplementing it with calcium and magnesium (5 to 1 ratio) if it helps to address the problem.

How do I get rid of it?

if you foliar feed these could be FFSD's
how can you be sure there are NO pests?

 

[Helmut79]

I'm not foliar feeding and I can be sure there are no pests, because I have looked.

Have you checked with a jewelers loupe? Cause I see atleast one leaf with noticable chewing on It. Can you take pic of bottom ofone of the infected leaves?

Looks like thrip damage. If you put a dark piece of plastic down like trash and give your plants a good shake makes them easier to find.

Looks like thips

I had thrips, and those mutherfuckers are TINY, like with a magnifier they were almost impossible to see. I would check again with a 100x mag, because it looks like bugs to me, especially as it is on almost all your plants and your nutes should fine.

I agree, if he hasn't dealt with thrips before it would be easy to not find the larvae on the underside of the leaves, they are very tiny and you would need to scan a leaf slowly with a powerful magnifier to find them.

Thank you very much for all the responses. Got just back to my computer and read what you said.

I couldn't imagine pests could be so little that you wouldn't be able to see it with a naked eye. Or could I?

I would go back and try to spot them before buying myself a magnifier, and then I'll post back results.

It will take me some time. In a meanwhile, could you please help me to get prepared for getting rid of them?

How bad are they?

It's possible to see them with the naked eye if they move or if you already found one with a magnifier, if they are motionless you will not likely see them with the naked eye.

Wow, just found out I got bugs. You were all right about this. Thank you very much. I'll now read about those bugs to understand the situation.

This is what I used when I had them, works well.

Thrips aren't bad. There are some sprays you can make with soap to dry out there bodies or neem oil will work. If you don't want to spray them with liquid you can get pyrethrum bombs and bomb the room. I've used pyrethrum against spidermites with good success. Just make sure the spray from the bomb doesn't land on plants or it will burn them.
