Help, pests in flower how to identify and treat
n1mbu5started grow question 6d ago
Can you help me identify the pests? I ma showing a leaf with necrosis and what I think to be eggs, the microscope pic is of what I think are the eggs, the guy at the grow shop thinks they are spider mites but I'm not too sure he didn't seem to look at them properly tbh

This is not typical of spider mite damage and their eggs are viable with the naked eye if you have good vision same with the mites themselves on the underside of the leaves.
Spider mite damage looks like fine white dots on the leaves. Won't need a magnifying glass to see em.

this is a image from my one grow that has spidermites, they are hard to see but zoom in and you can get em. but notice the fine white speckling on the leaves, that's mites.
This looks like a drastic PH swing and the leaves are suffering. the zoomed in blurry macro pics are almost useless but I think what you are seeing as eggs is really trichome heads. All parts of the plant make trichomes just the majority of them are in the flow buds.

Doesn't look like pest damage to me either.
Could be nutrient issue.
It can also happen if the plants have been indoor or in soft light and then go in the sun on a warm day.
If they're not hardened off they can burn easily.

I wouldn't say it was through a pest either. There is possibly something off with your nutrition uptake. Next watering test the PH of your runoff. If that's way out of range you may have a lockout.

Ich stimme mOuse zu, sieht eher wie ein starkes Problem. Dem PH und somit mit der Aufnahme von Nährstoffen, hast du schon deine Runoff kontrolliert? Der PH wert solte zwischen 5.8 und 6.5 liegen und EC wert solte man auch kontrollieren der solte nicht über 2 sein.
Spinnmilben und minerfliegen/Käfer sehen anders aus. Bei spinnmilben wird die Pflanze mit kleinen weißen fäden bedeckt wie Spinnweben. Bei den minerfliegen sind es meisten weiße längliche Flecken dort wo sie das Blatt durchbohrt, so wie tunnel. Also denke ich nicht das es von insekten kommt. Also habe bis jetzt noch keine solche Schäden durch diese gesehen.

Looks like classic leaf miner damage to me. The trails and blotchy necrotic spots between the veins are a giveaway. The eggs under the scope could be leaf miner larvae or eggs, as they lay them inside or just under the leaf surface. The best course of action is to remove the affected leaves to prevent the spread, and consider treating the rest of the plant with a product like spinosad or neem oil. Keep an eye out for any new trails or flying adults.
