That temp is fine it will do damage over 90 degrees keep it round 83 88 at most.Humidity can be in the 50 -60's range even 70's but kee it kinda low And durring flowering keep the humidity down to like 40-37 just so u can avoid mold problems if they were to occur. Ive always went by the hotter it is the higher the humidity should be.If you counter the heat with high humidity the foilage will be more dense so it wont burn as easy.Not to high humidity tho keep in mind..."it will raise they heat a little the higher you go in humidity"If you have alot of heat with low humidity like 20-30 range your fan leafs will be paper thin and wont be able to hold up against the heat. So just keep a thick, dense, lush canopy of leafs with 83-86 degrees and 50-65% humidity the whole time threw veg with complete circulation with fans above and always below the canopy...u can fit up to 1 plant every 1'x1'x1'x1' square foot so id suggest tht depending on ur area of grow...if you need to know more on that send me a private message id be glad to help or on here
