Over the last few days I have begun to creep my ppm's up to about 850-900 and have seen tremendous growth. Since the tips just now showed a slight sign of burning I think I finally found a comfortable ppm for the week. On some of the plants, not all, the new growth comes in lime green and then fades to a more normal green over a few days time. What should that be telling me? It confuses me when one or two plants exhibit behavior that is different then another set of plants only 3 inches away.
