What is this?

[mountainNick]

Hey all, I have had some thrips not long ago, applied neem oil for 2 weeks now, I found the source of the thrips so that problem is virtually gone but i have this on my healthiest plant and on a seedling:

This is the bottom leaf

Second set of leaves


Looks like it is working its way up, I just transplanted yesterday (big one), will be starting nutes soon (bio vega)

If anyone has any idea or recognizes this please leave a post, may you all have a green day

Bless

Leaf miners, dude you are going to have your hands full, you might as well start over, because the only real way to rid of them is to remove affected leaves, they burrow down deep in the leaves and plant there larva, that NO pesticide can absorb in there to kill them, with them being so early stages of life.... you are in a big mess now

For more information about it, check my sticky at the top of the forum called complete guide to sick plants,pH and pest troubles; scroll down to leaf miners.

Man, I am sorry about that. Thrips don't leave squiggly lines, they leave marks just like mites do, but a little bigger. These plants outdoors at all? In and out?

Trust them...leaf miner...

Ok i know what the problem is, i looked closely at the leaves and saw larvae looking things in the leaves, but only on the leaves with thrip damage on them, so it must the eggs from the thrips hatching, eating the leaf,and moving around in tunnels in the leaf. Im gonna water the plants with neem every month (neem stays in plant for 4 weeks after intake), and spray on foliage every week, this way there is no way any creepy clawlies are going to be able to survive like that. If anyone was wondering the larvae are yellow and EXTREMELLY small, could be leaf miner, either way they are not gonna stick around for long
May you all have a great day
Peace

Ya i am growing outdoors. I dont think it is leaf miner, the leaf do suggest its this but i havent seen the insects or worms of any sort, I think it would be a good idea to cut these damaged leaves

mate, many species of leaf miners are moth larvae so you are unlikely to see the culprits unless you do a night shift with your plants.

Check out the larvae I got out of one of the leaves I cut:

This my friends is thrip larvae, problem is solved by simply squishing the bugs between your fingers but if damage is too much on leaf cut the damage off
Peace

That is not thirp larva, that is leaf miner larva.

Check this picture out.

Thrips leave damage mark to that of mites, that is why people think they have mites or thrip larvae because the damage is nearly the same.

NEver seen thrips make that big of damage mark with sqiggily lines.

Check this picture out, this is what leaf miner larvae looks like and it's identical to your picture.

Thrips do put there larvae under the leaves, but so do miners and

Another good link showing there life cycle.

Here is a closeup of leaf minor larvae and it has the same black spotting on the ends of the larvae that you have in your picture.

Leaf miners are also bigger than thrips if I remember correctly.
The bigger the damage the bigger the pest.
Thrips strips off chlorophyll, same as spider mites, miners make a wider damage with zig zag because they move and eat under the leaves and goes any which way it wants.
