I planted two big beefs and two celebrity variety plants in containers for my early go to's. Everything the same, same location, same water, planted in the same potting soil and peat mix, same fertilizer. Big beefs are now over two feet tall and celebritys are about 18 inches. When I walked out to water this morning, the two celelbritys had copper colored shiny spots covering the lower leaves. Big beefs green and healthy. What might the spots be and is there that much difference in disease resistance among plants varieties? The celebritys are now not "celebritys". They are in the corner of the yard by themselves.
