Disease or nute problem? Help please

Hi. I've got 8 plants outside, growing in 7 gallon smart pots, guerilla style. They've all gone into flowering over the past two weeks.
Recently, they've all been hit with this terrible brown spotting that's working its way up from the lower leaves.
Any idea what's causing it? Is there anything that I can do to fix it?

it spreads very easy so if tending any other plants after those be very careful, u cant cure it just hold it off if its in the sugar leaves I would burn them now,not worth the fight

Is this the same thing??
One of my girls has a dozen or so leaves with these spots.
If its a fungal thing can someone tell me the name of it? Till i figure out how best to fight this should i just remove all leaves with spots?

Thumper, your advice was spot-on, and may have just saved my plants this year. According to the package directions on the copper fungicide, I gave three weekly spray treatments with a garden sprayer. The yellowing and spotting continued to spread, but much more slowly, after treatments 1 and 2, but after I sprayed for a third time last weekend, no more leaves have been infected. They were looking good and happy today.
