Cannabis leaves spots & holes?
My two plants have had small yellow/white spots for a few days, and they're getting more numerous, including small holes. The third plant of the same variety has nothing like that. I would rule out pests, since they're indoors and fertilized regularly according to the exact instructions. I would also almost rule out sunburn.
Does anyone have the same problem or know what is going on here?
Thanks in advance🫶🏼

At first glance, I would say that the pots are much too small for the plants.
The second glance says that pests are often towed with the earth, especially if they are cheap and unsuitable for cannabis cultivation.
The stains look like "spit-tubs of grief mosquitoes" which are typically left behind when grief mosquitoes absorb substances from the leaf surface.
Not dramatic. Yellow plates can help. Better still nematodes.
It is also important to regularly scan the leaf undersides (with a magnifying glass) for pest attack.
Thank you.
Currently I have not seen grief mosquitoes yet, but is well possible👍🏽
And I think the pots look rather small from the angle, but I'll knock again next week.
Thank you
A fist formula says that cannabis plants above the earth can grow about two and a half times as large as they have space in the pots.
That can happen. Cannabis is very robust. Keep growing.
Probably be a pest, just because they're in the house, that's what happens anyway. They will survive.
Good Morning.
These silver spots are pretty sure an infestation of thrips, these are the most common pests with the grief mosquitoes.
with a little neem oil you can fight the pests
