Yellow spots on leaves

CloneKingzstarted grow question 5y ago

What would cause these little yellow spots on leaves? Feeding 150ppm calmag, 450ppm megacrop I’m coco/perlite. Water source is 0ppm, no chlorine. Only on this one plant and don’t see any critters. Light source is MH 18” away.

You say no critters, but that's thrip damage. I'm all but 100% sure. Check underside of leaves. They look like tiny worms, usually lime green. Even if you can't find any, I would still treat for it. Best of luck with the bastards!

Thanks for the solid answer! I literally looked under every leaf and only found two white fellas. None the less need to start treatment and get rid of these guys.

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn?

Deficiencies? Brown spots, yellowing and purple stems What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.
