How do I identify specific nutritional deficiencies in my begonias?
As an avid gardener, I've become quite adept at assessing the health of my orchids, but I'm finding begonias to be a different challenge altogether. Some of my plants show stunted growth and leaf discoloration that has me questioning their nutritional needs. I'm in a small apartment with limited access to natural light, so I've been relying on artificial lighting and a balanced fertilizer regimen, yet symptoms persist. I've tried adjusting the feed schedule and even switched to a liquid fertilizer, but I'm at a loss when it comes to pinpointing which specific nutrients might be lacking. Can anyone help me understand how to accurately assess nutritional deficiencies in begonias? Any visual cues or tests I could perform would be greatly appreciated!
