Sunflower w/ yellowing leaves
Hi. I hope someone can help because I'm really worried for my sunflowers (4).
Few days ago the older leaves closer to the bottom have been yellowing one by one.
Yesterday I just transplanted them since that was the plan when the materials arrived.
Today an increasing rate of leaves yellowed and seemed worse than before.
After researching I figured it might be nutrient deficiency by the looks of one of the distinct leaves but I felt I might be wrong since repotting it the soil is refreshed by new nutrients no? I questioned myself.
Since that there was a number of differing factors after the transplant: less sunlight, bigger pot.. more soil..more water holding capacity.
Hope someone can enlighten me before my fear for worse.
