Cannot Diagnose After Reading and Advice from "Experts"

I have 10 beautiful sativas currently 7-9 feet tall. Outdoor and started from seed.

They are right at pre flower stage. I had to destroy one male.

Using the Fox Farm liquids (grow big, big bloom, tiger bloom per directions.

Was doing great till about 2 weeks ago.

Now have yellowing leaves with brown spots. I see no living organisms except for an occasional spider or lady bug.

No browning of tips indicative of nute burn,

Problem is not only on lower leaves.

At first I thought dying leaves as energy goes to flower but not sure and the spots
concern me.

2 local so called experts had differing opinions one said "Septora disease" the other said nute deficiency but did not know what nute!

To my eye many of the nute deficiency pics look so similar.

I have attached a couple of pics.

Anybody?

I'd hate to lose these plants cause I'm thinking a big yield at harvest.

And yes I planted too close together. Lesson learned.
Never expected this type of growth! But hey it's a weed.

Thanks
