if your growing indoors look for flies around your soil area or on your leaves. if you see 1 there are more. I tried some white fly traps and that took care of my problems. caught probably 20 + over a week then no more chunks of leaves missingYep, if pieces are missing, somthing is eating your leaves. Check them over very close - make sure you look at the underside of the leaves, as well - caterpillars like to hide there.
