I was wondering if that was the cause of brown tips and edges also. I have a magnifying glass and couldn't spot one mite so I know it isn't pests and I haven't given the plants anything but good 'ol water which pH was 7. And the soil's pH stays at 7 since there isn't really anything in there. Don't know what it could be so it has to be heat..any suggestions?
