That's my first thought as well! If the affected areas are mushy, I'm going to say bacterial infection. I don't know the contributing factors (maybe leaf damage during repotting, maybe sunburn) but if the areas get larger, I'd cut them away asap!

Jason is giving the same advise I would give, if the plants were mine. I cut back to healthy tissue, then spray the cut with alcohol, then dust with sulphur. Should be O.K. but keep an eye on the newer growth, however. Remember, the sun is getting stronger... Betty :-)
Hi Vicki,
I don't have a lot of experience with 'Phyton 27', but as with any fungicide I would recommend you use it again only if the problem persists. At times a second application might be necesary, but if the leaf condition is not getting worst and seems to have improved, I would stop using it.
