You've got some sort of insect problem and what I find interesting is that folks generally want to be able to SEE the things to know EXACTLY what kind of insect before they start treating... and that's kind of silly to me. There's isn't one special product for thrips and one for spider mites and one for... you get the idea. There are organic insecticides that will treat leaf SUCKERS (which you have) and leaf EATERS... Anything with Spinosad in it will kill off the leaf suckers along with their eggs/larvae... and BT (Bacillus thuringiensis) will take care of the leaf eaters (they take one bite of the leaf and decide to have lunch elsewhere but actually go off and die). So get yourself some Spinosad or Dr. Zymes Eliminator... these are two organic insecticides that will quickly take care of your problem... Good luck!

The Amazing Dr. Zymes will nip this right up. So will nicotine poison water, if you don't have the funds to buy pesticides. You can take a couple cigarettes and soak the tobacco in isopropyl alcohol for a bit. Then, strain it through a coffee filter and into a spray bottle. Fill the bottle up with water, call, shake well, and hose those dirty buggers. You can get a sample of Dr. Zymes from www.doctorzymes.com/wizard I hope this helps.

@Ju_Bps I didn't seem it at first either but once they got bigger I've did notice them, on top of it my leaves looks like they been sprayed with silver hope it make sense. Whenever I have thrips I use Guard'n'Aid For Thrips Keep checking your leaves from underside and start asap on fighting with those fkers

Looks like thrip damage. I've had them loads and know it quite well unfortunately. They are incredibly tiny at the start of their lifecycle and difficult to spot, but find they usually hide in the veins of the leaf (on top) or in the groove down the petiole is their favorite highway to the leaf. Spider mites, aphids and whiteflies love hiding under, but thrips seem to favor the top. Poison sprays are not very effective with them, predatory mites are best, otherwise a foliar spray with Diatomaceous Earth. Luckily they are not a massive problem as long as you don't let them get out of control, but not having them is even better. :P

Da schließe ich mich den beiden vorherigen Antworten an. Thirpse vielleicht Gewittertierchen 🤔 Irgendetwas hat da von deiner kleinen Lady genascht 🤨 Ich wurde Gelbtafeln aufstellen und schauen was da in die Falle geht. Dann halt Gegenmaßnahmen, also entweder Nützlinge wie Nemathoden oder ein Insektizid😄

Hi there Doesn’t look like any sort of deficiency I’ve seen so I’m guessing you’ve got some sort of bug/insect issue, I would get some sort of plant friendly spray/repellent for them Best of luck 🌱
