Hi Josh! You're definitely not alone — tomato leaves can be very expressive when something's off. Let’s break it down:
🟢 1. Leaf Curl / Distortion
If the leaves are twisting, curling, or looking misshapen, common causes include:
Environmental stress: heat, wind, or inconsistent watering
Over-fertilization: especially high-nitrogen feeds
Herbicide drift: even a small amount from nearby can affect tomatoes
In most cases, if it’s just a few affected leaves, you can pinch them off, especially if they’re older, lower leaves. This can help airflow too.
🟣 2. Purple Leaves on Seedlings
Purple coloring on tomato seedlings is usually a sign of phosphorus deficiency. This often happens when:
Soil is too cold (phosphorus becomes less available)
You're using a soilless mix without added nutrients
The seedlings are underfed
✅ Try moving the seedlings to a warmer spot and giving a balanced liquid feed (like a diluted tomato fertilizer or a complete organic mix). Once they go into the ground and warm up, the color usually normalizes.
If you have pics, I’d be happy to take a closer look — it’s much easier to diagnose visually.
Hope that helps, and good luck with your tomatoes! 🍅
