Temp has been around 80, humidity about 70% and AC going in today.

Here are the pics....I hope you can help. Sure is troubling to see your plants have problems. Thank you for your help. I have searched the diagnose sticky and I think I know what is wrong, but my I lack experience. Thank you for your input. HELP!
Sounds like your soil is WAY too acidic. To go from ~7 to almost a flat 6 means your soil is likely sitting around high 4's-mid 5's, depending upon how much water you're using each time.

Flush your soil.
