Indoor plant help
I am growing a few plants indoor due to the climate zone I live in and the plants I am growing. At the moment I have a Hawaiian Hybiscus, Salvia Divinorum, and a Pinapple Sage. All of which blew up from May-June though now toward the end of July they are all seeming to thin out and their leaves are browning/dying.
I read that being that they are tropical plants they may not be getting enough humidity since I'm an a dry climate and our central air draws out moisture, so I have been misting them 3 times a day. Though it is not seeming to help.
I'm assuming since it is effecting all 3 plants it could be some sort of virus or something to that affect. Any help in the matter would be greatly appreciated!
(I will post pictures of the plants once I get home from work)
