having it that hot would probly slow the growth down.. always use boiled then cooled water it is better loweres chlorine levels and takes out any bacteria you can still ph it down or up whatever but yea boil first you need to find a way to lower that heat some plants can take it others cant depending on your fan set up ive seen ppl put a bowl of ice water with salt init behind the fan the salt will super cool the water/ice so the air its blowing around will be slightly cooler not sure if you meter will do humidity
think you said 33%? thats not too bad me thinks you dont want it to humid otherwise root might set in

get your temps down start using boiled water this should sort your problems
