Is this "damage" caused by a pest?

I tried another forum- “diseases” - with no answers-- so I am trying here.
Is this “damage” on these plants caused by a pest?
If Not, any idea what would/could be causing it? or even what it IS?

we bought these plants from a dispensary. This one plant came with these “spots”/area, but they are getting bigger and more of them.
We do know that they were in a grow tent indoors. do not know soil type, water type, fertilized or not, etc.etc.
Thank you in advance.

Looks to me more likely that some nutrient solution was spilled on it, or old light burn. Not so much on the light burn though. But still possible.


@Covertgrower : Thank you~ much appreciated.

@Covertgrower He did mention the spots are getting bigger. Do you think spilled nutrient solution would still be the case?

The other factors I consider knowing that these were clones from a dispensary. During transport, the leaves may have suffered damage, and there’s a certain amount of “unknown “ history when someone else cares for a plant. Nutrients spilled may not show up for days, neither will transport damage.
All new growth looks great, so unless it’s spreading even more to the new growth, I wouldn’t be overly concerned. @Growyourown @Yochaniel

But as always it’s important to stay vigilant and watching for pests.


Okay, putting it that way makes a lot more sense lol


the plants are turning yellow. i will post pics later today-hopefully
