The leaves of my tomato plants are starting to look purple along the veins and on the underside of the leaves.

Purple leaves are an indication that the plant is not receiving enough phosphorus. If you have been using a diluted fertilizer for the first 3-4 weeks of the seedling&#x27;s life, it may be time to increase the fertilizer to full strength. The phosphorus content (the middle number on the fertilizer analysis) should be at least a 3. <br/> <br/>

I needed to read this today! Thanks for the info! I have just repotted the seedlings and hopefully they will be getting what they need now.
