Is this a pest problem

I think they are overwatered, roots arent able to picks up nutes properly. But need more info on the grow.

If you're worried about pests, those yellow sticky traps are best for diagnosis, not so great for control.

Systemic like this makes me think a failure of nutes. Test the pH of the runoff and use regular clean water (test the pH so you can tell if it gets higher or lower).

It’s probably under/over watering and a little too much light. Scope one of the bottom sides of the leaves to be sure though

Do you mean to look for pests ? I’ve looked through the whole plant and haven’t found any bugs or webs. I do have some fungus gnats I’m dealing with currently but from what I know they don’t cause this kind of damage.

I had similar growth. Turned out it was thrips :/ Check for those f*ckers.

If you are fighting fungus knats than its to wet, give it a dry cycle.

If you think it is a pest issue… flip the leaf and examine with a loupe….

[u/SecureJudge1829]

Without seeing the actual pests, I’d say the damage looks a lot like a thrips infestation beginning to grow out of control.

No

What would be causing this ?

[u/cultivars_ → u/SherbertAgreeable517]

Several things, could be a pH imbalance causing a lockout, could be root bound, could be lights are too intense.

Not sure what your fertigation method is, or the substrate… so hard to diagnose
