The fact that the damage is SO localized makes me say bugs, not deficiency. It's not a damage pattern I'm familiar with- whiteflies are certainly a possibility! A yellow sticky trap will give you an answer in just a few hours.
stinkyattic Reviewed by stinkyattic on . Plant Problems For First Time Grower Can anyone help me diagnose my plant problems? One of my plants has some yellow spots on its lower leaves. I transplanted the seedlings about one month ago using Miracle-Gro Moisture Control soil. The plants have been under 24x7 light since seedlings. I have only used Miracle Gro's All Purpose Plant (24-8-16) Food once about 3 weeks ago. I would gladly appreciate any replies. Thanks my fellow growers.
