Yes sir, have a look under the leaves, spot anything that resembles "red sand particles" dont think thats the best description but either way have a look under the leaves and see if you spot anything unusual.Looks like bites from mites
Can you see any webs on the serrated edges of the leaves. Try to clip off any leaves that have the mites and probably have to spray something like insect soap.
Those white spots almost looks like white mitesno webs
Yes its better than to spray in flower, i wouldnt spray anything in flower. Veg is completely safeanother this am from iphone cam
i have some soap i can spray em down they are still in veg
i’ve pulled off a good chunk of the leaves that have these spots and i can find anything under with the microscope .. sigh .. :)
