مخطط نقص العناصر الغذائية للنباتات

I’ve been growing peppers for years and always guessed at deficiencies, but this chart finally makes it obvious which yellowing leaf means what. The breakdown of both major and minor elements is exactly what my messy garden notebook was missing.

The layout is clear and easy to follow, with both major and minor elements broken down simply. I've been using it to troubleshoot some yellowing leaves, and it's already saved me from over-fertilizing twice.

Finally, a chart that actually shows both major and minor deficiencies side-by-side. I laminated mine and keep it right next to the potting bench for quick reference.
