yellowing leaves, nutrient feed/ph question

Hi, I have some plants that are finally five feet high and budding like crazy but whole branches are showing yellowing leaves, and the bud sites drying up. I would guess nitrogen is a key here but my ignorance leads to onequyestion I have not considered. In getting the right ph for cannabis I assumed the base water was the measuring point. but maybe my problems have to do with the lowered ph in my note feeds?
So close . . .yet, uh I can't even consider having the alternative. Stale. overpriced dispensary weed.

Not much to go on.. Gotta pic?

Yes, but tomorrow so as to not screw up the 12 and 12. Will post.

Here is the plant outside. This is my first grow since the renegade plant in the state park days, so don’t be timid in criticism as it is all helpful.

Putting pests aside...

Looks wet where you are, have you been getting a lot of rain lately? Outside grows in pots sometimes get nutrients washed out from excessive rain. To answer one of your questions, I check water PH every time, when adding nutes I check water PH after nutes added then adjust PH. Do an experiment and catch some rain water and check the PH, it might surprise you.

Great advice, and very helpful. Starting the experiment from this am.
