What bug is causing these bites in my leaves and how can I treat it. Have already tried Neem with no effect. Plant is sitting outside in northern Germany. Interestingly only DoSiDos is attacked while my other strains are safe from these bugs

Based on the patterns visible in the close-up images — especially the tiny, irregular, squiggly or serpentine trails and circular holes in the leaves of your Do-Si-Dos plant — this is very likely leaf miner damage, not caused by a chewing insect like a caterpillar or beetle, but by larvae (usually of flies or moths) that burrow inside the leaf tissue. 🔬 What are Leaf Miners? Leaf miners are larvae of various insects (mostly flies from the Agromyzidae family) that live inside the leaf layers and create tunnels or mines. Their damage looks like: White or yellow squiggly lines Blistered or transparent patches Small circular entry/exit holes (as you can see in your photos) They are protected from Neem oil, because Neem works on contact or ingestion — and these pests are inside the leaf, not on the surface. ❓ Why Only the Do-Si-Dos? Some strains are more palatable or vulnerable due to leaf structure, terpene profile, or nutrient makeup. Leaf miners can be strain-specific in their preference, especially when populations are small. ✅ How to Treat Leaf Miners (Better Than Neem) Here’s a proven, multi-step strategy: 1. Remove & Destroy Affected Leaves Immediately remove all leaves showing mines or trails. This halts the current life cycle (the larvae will pupate soon and reinfest). Dispose far from your garden (don’t compost). 2. Apply Spinosad or BT (Bacillus thuringiensis) Neem won’t work well on leaf miners inside the leaf. Use Spinosad (natural bacterial insecticide) or BT — both safe for cannabis and organic. Spray in the evening or early morning to avoid UV degradation. Brands: Captain Jack’s Deadbug Brew (Spinosad), or BT Thuricide. 3. Sticky Traps (Yellow Cards) Adult leaf miner flies are tiny black flies — attracted to yellow sticky traps. Hang near the plant canopy to trap adult flies and reduce egg-laying. 4. Prevent Future Infestation Consider covering the plant with fine insect mesh (like Agribon or anti-insect netting). Keep checking for new mines daily for 1–2 weeks. Bonus: Beneficial Predators You can introduce parasitic wasps (Diglyphus isaea) — they lay eggs inside the leaf miner larvae and stop the cycle biologically. Available online from biocontrol suppliers (often used in greenhouses). 🔁 Summary for You (TL;DR): Problem Leaf Miner Larvae (likely Agromyzid fly) Symptoms Serpentine lines & circular spots on leaves Neem effective? ❌ No — larvae are inside the leaf Best treatment Remove damaged leaves Apply Spinosad or BT Use yellow sticky traps Optional Introduce beneficial parasitic wasps Location note Northern Germany = moist climate, higher miner activity

B.T. - ........Bacillus Thuringiensis spray........biological control .........will kill nearly all leaf chewing insects and is safe..........unlike Neem. Look for it in the organic gardening section of your local plant nursery.

Moin Seabass. Wir haben hier in Norddeutschland Wetter. 😏 diese Stellen sind durch Wind beschädigt. Da wird das Blatt geknickt und reißt minimal ein. Diese Sturmschäden hab ich auch überall, die machen aber nix. Wenn du schon mit Neem dran warst, dann sollte eigentlich auch nichts mehr beissen oder saugen.

Hey bro looks like some kind of leaf chewing pest for sure. Outdoors this time of year, it could be leafhoppers, beetles, or even tiny caterpillars depending on the area. The weird part is yeah—some strains just seem to be bug magnets while others get left alone. I’ve seen the same thing with a couple of mine. Since Neem isn’t working (honestly, half the time they don’t care about Neem), I’d try: ✅ Pyrethrin spray—it’s quick knockdown, but careful near buds. ✅ Or just do daily leaf checks and manual removal if it’s not a full-on infestation. ✅ I’ve also used a light garlic or chili spray to make the leaves less tasty. If the damage is minor and the plant is otherwise happy, they usually power through it without drama. Just keep an eye in case it spreads or you spot the culprit. Good luck bro, outdoor grows always come with some random surprise. Good luck with the rest of your grow 🤞🍀♥️

buy one of those cheap meash 'greenhouses' pyrethrines are a kill on contact option. Buy a concentrate and dilute for use for best bang for buck. Neem is useless unless you like its shitty smell.
