Brown spots and something eating my leaves please help

The strain is true OG. In a green house. I'm using foxfarm happy frog reused from last season because I didn't have money for new soil. All I gave the soil last year general organics bloom nothing else. Someone please try and help.

hey man, the pics I the second post almost looks like thrips but when I zoom in its quite hard to clarify that. either way its obviously some kind of insect. so id go with some side of insecticide whether you go for a more organic or chemical approach.


it if was caterpillars, you would most likely find some on the plants somewhere.

I've had thrips more times than I can care to remember. And the Damage they did never looked like that. I am not doubting u. Ill get some spinisad that has always worked for me. But way do u say about the bite marks on the leaves. I've never seen thrips put holes in leaves like that. Can thrips eat holes like that because from my research the eat the chlorofil the green from the leaf 1 week ago these plants were beautiful be sign of anything except good growth.. Any other idea from u or anyone else would be appreciated.

Spinisad it is then. I checked very carefully for caterpillars. Didn't find any at all. And yes my partner said when he goes in to water there is little white moths everywhere. Thank you.
 
If anybody has any other input or needs more info. Please don't hesitate. This is my medicine. Thank you all. This is a great community
 
Dude i have exactly the same problem. I found one of the lil buggers. Caterpillars stunted one of my plants...damn moths! Spinosad was my go to.
 
Thanks everyone. Spinisad was the first thing I thought of as well but this is my first greenhouse grow and I've been growing for over 6 years and have never seen damage like this. If any body else has input please don't hesitate. You are all great. I was freaking out and within a half hour 3 people came to that same conclusion as as I did before even posted. I know indoor very well. But this green house set up just throws me in a loop if you all know what I'm saying lol. Anymore input would be much appreciated. Thank you all.

It's possibly one of the Leaf Skeletonizers.

Spinosad would be the control for them also.

It may already be to late but you may be wise in setting up some moth traps OUTSIDE your greenhouse. If you've got ANY light sources in the greenhouse at night, they will attract moths. A UV bug zapper might do you some good as well. Maybe try a bug zapper with moth hormones just to be sure.


Also, if it is too late, you can be ready for next season.

Well I havr 12 plants in the GH. And 4 of them have about 60% damage 2 of them are around 20 percent. The other 6 are virtually untouched. Any recommendations. Also do caterpillars dig into dirt like worms??
