I have beans planted in large containers. I usually water in the morning. My plants are entirely yellow (stem, leaves and leaf veins). I purchased organic fertilizer 1-3-2 and added, which I think burned the leaves. Last night around 4pm I checked and the soil was dry. Could my plants be under watered?
