Leaf spots

[Okietrapper]

Been fighting this on some of my outdoor plants all year they are all heavy in flower now and losing lots of lower leaves. The ones that have lots of spots start at bottom and go at least half way up some even more. I ph water from 6 to 6.5 every time. I use rain water and have to ad a little baking soda when I ad fertilizer. Been using Jack's classic bloom since the started flower. Some had the spots before flowering. Weather sucks here 90 to a 100 every day and high humidity. Thanks guys I need lots of help I'm a newbie

When grow outside I wouldnt worry about spots and scars only if actual problem. And using baking powder as a adjuster would probably thicken the solution.
