Bro only time u leave it 40-50% in flower is if u ignore vpd altogether! Guesstimate u will prob need 50-55% with temp if 79 but use calculator it will tell u!
some books I have also say this. So much information from so many directions its kinda hard to pick out what is good information and what is bad info as a new grower.
Exactly enough to drive you insane.. I remember seeing a guy on Reddit that his diagnostic box that he would take to friends house to help out had 3-4 ph meters.. he said they all read slightly different and he lets them fight it out
If I’m looking at that right you are lower then 1.6 vpd
