Leaf malformation or bugs?

I've had plants with torn or shredded looking leaf section before. It's a bit of a mystery. Sometimes when i lift my fabric pots by their handles a leaf will get pinched and ripped or damaged in some way. Twisted and retarded growth is usually Boron deficiency but that tends to be in new growth. It's likely that you have a bug on your plant somewhere. If you can remove the plant from the grow space, take it out and bring it somewhere where you can be comfortable, and take your time to looks carefully at the plant, especially the undersides of the leaves because thats where bugs will tend to reside. If you don't find a bug on it, then take another plant out and check it. I'm sure there's a bug somewhere that's eating them. The damage is pretty minor though so i wouldn't panic. It appears to be a bigger bug, which is good. It will be easier to spot and eliminate. When you have spider mites or thrips or aphids it's a different story. Keep a close eye on them if you don't find any bugs. It's possible that the bug died, or left the space. In the future, don't come in from outside and go right to your garden. Especially keep your shoes you wore outside away from your garden. If you were laying on the grass in the park or your back yard, it's likely bugs are on your clothes and are hitching a ride so be careful! Change clothes if you can't wait a few hours before going in to work in your garden.
