Fruit at the band for your species: 18-22 C for P. florida, 22-26 C for P. sajor-caju and P. flabellatus, 14-18 C for P. eryngii. Warmer than its band, sajor-caju turns brown and thin.
Relative humidity, RH, is the water in the air as a share of the most it could hold. The manual says all Pleurotus need 75-85 per cent RH during fruiting; TNAU gives 80-85 per cent at 23-25 C. Raise it by spraying floor, walls and air two or three times a day and hanging wet gunny at windows.
