Flowering week 5 temperatures and Humidity range??

Yeah should be good, depending on the strains flowering time, you will want to keep temperatures at 67 or below once the plant devotes its energy to ripening, this is when most terpene production happens and it's vital to lower temps if you care for dank smell. Myrecene for example will start to degrade below 67, make sure never to let it get before 64 as manganese will start to have problems uptaking through rootsystem below 64 and will seriously effect the buds ability to fatten if you try for purples to early. Humidity is good but make sure it's not dipping below 35. Again strain specific if your plant is not native to lower humidity try bump it up, it's absoloutley vital during flowering everything runs in optimal harmony. Wish you the very best brother, good luck.
