random brown holes in leaves

[Medchief]

Anyone know what causes these, I don't see lots of this type of damage but I am concerned about what causes it.

ya i have identical damage im curious whos doin this too lol

 

[MPD]

Are these necrotic tissues? Is this an indoor or outdoor grow? Soil or hydro? Give us some details. What's the pH of the grow medium? What is the feeding schedule and what amendments in what proportion are being used? If indoor, how many watts/SF at the plant deck are being provided?

I know it sounds like a lot of questions, but there could be multiple causal elements here that need to be eliminated.

MPD answer to your questions

Are these necrotic tissues? sorry I did a quick search to see what this meant but couldn't find anything related to marijuana growing. Can you clarify?

Is this an indoor or outdoor grow? Outdoor grow. My first actually, AK47. Growing in a suburb of Portland Oregon. Our weather has been in the 70's and 80's almost all the time since June when I planted them from a clone.

Soil or hydro? Soil.

What's the pH of the grow medium? I still need to research how to measure PH. It is growing in Miracle Grow Potting soil and has been doing well (see my other pics in the Outdoor Grow area titled "'AK 47 First Grow").

What is the feeding schedule and what amendments in what proportion are being used? The feed is in the soil and I have added nothing else. I am getting ready to get some blooming fertilizer as it is starting to bud (recommendations?)

Hope this helps.

Found the little Fucker. Either the Catbird or Robin that hang out in my garden took care of him. I'm looking for his family members.

For caterpillars BT spray is a good option. It's an organic bacteria that only affects the cats by making them unable to eat. Has no effect on the good bugs. Or if you can find a Praying Mantis put it on your plants, they love cats and grasshoppers.

they eat fast so the BT spray from amazon is $18 for 16oz, it really works well for caterpillars like orggrwr stated
