High pH levels in soil can cause nutrient deficiencies in tomato plants, leading to yellowing leaves and stunted growth. Iron, manganese, and phosphorus are less available in alkaline conditions, resulting in poor plant health. To correct this, gradually amend the soil with sulfur or organic matter like compost, which can help lower the pH to an optimal range of 6.0 to 6.8 for tomatoes.
