well you didnt say around 80 you said 89 max lol...around 80 on a hot day here or there is fine but if it commonly gets over 80 that is not good enough..ive done some of the same things thats how i know whats better so ill try to help but up to you if you listen or just do what your going to and learn the hard way...you do not want to hang the whole plant upside down at the end with all the leaves on it...the best way to trim is wet, so first pull all the fan leaves off and set in garbage pile now cut off a manageable section of a branch and snip off all leave tips with no trichs also in the garbage pile, then over a shoebox or something trim all the remaining leaf that is sticking out around the bud do not cut leaves out of the bud just shape them, then let the trimmed branches dry a few days and as soon as they are just a little crispy to the touch, cut the nugs off the branches and finish trimming any revealed sugar leaves and then jar..take all the slightly dried sugar leaves and do what you like, hash,brownies but let them dry all the way first..now back to growing it first, you really dont want the temp to go over 78 about 72-78 is the sweet spot and you need to stay in that range..your already half way through flower it sounds like and your using flouros in an over heated room the outcome will not be proper quality or yield though you may get something you can be proud of that will get you high, it surely will not be top shelf..idk what kind of fan you have exactly but you should run it all day and monitor the temp for that day..if it stays around the mid 70s then you need to leave it on whenever the lights are on, once you have the temp issue worked out (which in the future do a few days before you add the plants) and IF you are using the nutes right and have good soil and can get that 600 watter back on then you will be set man! upload a pic i want to see how your plant is looking much easier to give feedback
