Ok here is the problem. It is the 8th week and I have these problems. The first picture is a worst symptom because I already lost 2 plants. All leafs go like that and the plants die for a 2-3 weeks. The PH is good - 6-6.5; the temperature is between 22 and 26 C. The humidity is between 40 and 70%. I use Dutch Formula, I have air supply system with carbon filter (but the room is basement and sometimes smells bad maybe I have to put bigger fan for the air going in). I have climate control unit and everything I need but as you can see some of my plants are gone. The second picture is about all plants but the leafs are in this condition mostly near the floor. I clean the room almost every day and I'm trying to the job really professional. I will be really thankful if someone could tell me what are these symptoms -especially the first! Thank you.
