Leaves show blotchy, moist extremities. ... or is that a picture of the dreaded leaf miner? Check underneath for clusters of small white eggs < 1mm long but thin. The egg cases often hang on after the larva has set off on its trail of destruction. Plenty of guidance elsewhere on treatment.
Cut back on the watering. Give the leaves a chance to repair, if they remain in poor state remove them.
Only water in very dry weather.
