What is correct Temperature, Humidity, and pH level?

just curious because im pretty sure my room is pretty warm and am looking for ideal humidity levels and pH. my room gets almost up to 90 degrees F and humidity around 39. what should i be going for?

90 is pushing it to the max, growth will b slowed, 75-85 is opitimal.
Rh should be 40-60 for veg, and 20-40 for flowering.
assuming that you are using soil ph should be 6-7, maybe 5.5 to 7
hope this helps

Jorge Cervantes says 72-76 Farenhiet is Ideal, Soil Ph 6.2-6.8 and humidity 40-60%, That's for optimum vegging, seedlings need 90-100% humidity and flowering you want >40%
