One thing that we do at my greenhouse is to rub isopropyl alcohol on any spots that look suspicios. It doesn't harm the plant, it dries quickly, and it kills almost everything. Make sure that your bottom leaves are not coming in contact with your soil or the will start to develop issues.

Good Luck,
