Pale green leaves and marks

Hello Roll It Up people,

I write from Chile, I have a greenhouse with several strains, some of them in the soil (Afgnani, OG kush and white dragon) and others in pots (Og kush and PowerPlant)
The thing is that the ones in the pots are more pale green and have strange marks but no bugs. I have seen bugs but generaly there are normal spiders that eat them.
I nute with biobizz twice a week. The only thing is that the temperature rises to 32 C in for 2 hours and then drops.
My question is what can I do to make them look healthier and why are there marks when the ones in the soil doesnt have them.
Here the fotos and thanks in advance for any help.

It could be some kind off deficiency I'm no expert, but they actually look really healthy, try a foliage spray

Looks just like spidermites damage

That's what I was thinking. Those white dots are usually signs of mites. Check under your leaves for 'em, there small but you shouldn't miss 'em.

Thats the thing, i have been monitoring the bottom of leaves and found nothing.
Is it posible that the natural predators are taking care of the spider mites?
I say this because i have seen normal spiders living in the top buds and also very small number of ants wondering in the plants.
Cheers.

Outdoors mites are less of a problem.
Your plants look good to me.

looks like thripes. Thrips? Whatever

I "think" if you give the potted plants a wee bit more water they'll darken up.
Where I am. in Canada I can get a hygrometer that gets shoved into the pot permenantly so you'll have some idea on when you should water them. In my hydro table I know when i got it correct because the fans and plant will track with the light.

I think you could be right about the watering, i ll try that.
Cheers

I agree with Charface. Thrips/leaf miners.

Dont be fooled. In our area last summer we had an epic battle against spidermites in our soybean fields. Even battled them in our corn.

Fortunately for crops we can use chemicals that kill adults as well as the eggs. But unfortunately they do not deter re-infestations.
