do you see any webbing around the branches/trunk area? part of the problem appears insect related, mites if ya see webbing and eggs under the leaves and also could me a ph prob. parts of florida are notorious for the alkaline soil...need more info.

Looks like he has an insect problem, or it something in his ph as you said del.

Looks like it might be iron deficient.Also like Del says check ph and may have a mite prob.

Remedies i would sugest is ,give them a good complete liquid fertilizer every few days for aweek or two and spray with a general insecticide or if you dont like the heavy chemicals try some white oil then in about 7 to 10 days follow up with a general fungaside ,a copper type of spray should be fairly harmless as a fugaside...

For me it's just normal. I've got a few plants outside, and every week i take off several leaves like this or worse ( brown and dry ) and i don't mind. It's not dramatic anyway.
