try and get your temps between 70 and 75 during the day and 60-70 at night. anything higher then 75 for all 12 hours is stressing them. its ok to have the room heat up to 80 as long as its not for long periods and constant. they definately are a lil hungry, give them a lil flush with a mild nute but dont go overkill on the mixture. start them out slow so they dont "nute burn" which will fuck up your ph and can cause salt build up as well. give them some nitrogen for the next two weeks then flush em and switch to a no N and all PK mixture. in the first post, third pic, i notice that the leaf tips are curling downward, this is heat stress and improper watering/PH balance. my ladies personaly like a 7 ph. do you have city water or well water? city water is usualy shitty for growing. lastly, water in the morning as soon as the light comes on and not at night. im just trying to help ya out man thats all, dont take anything the wrong way...fellow patient here
