bugs r eating yr leafs

are you sure???

Can anyone confirm this is a bug issue? Someone else said it may be a ph issue, or deficiency possibly?

well i dont think its a ph issue on just one leaf. also if your meter is calibrated and digital it couldn't be right .wait like a few days and make sure it doesnt progress. it does look like possible insect damage . its not spider mites or fungus gnats for sure . the bites are way to big and those are the 2 that i have experience with . hopefully someone with more extensive insect experience will come along and help . but one leaf is no big deal man if it doesn't progress i wouldn't worry about it
