Hello –

Please check out this article for our recommendations on how to control Leaf Spot (https://www.planetnatural.com/pest-problem-solver/plant-disease/bacterial-leaf-spot/).

As for early blight, it thrives in warm, humid environments. Keeping water off of the leaves and watering the roots directly can help to mitigate early blight. Staking, pruning, and increasing the air circulation at the base of plants can also help to control the problem. Adding compost to the soil surface as a mulch and discarding infected plant matter (DO NOT COMPOST) are also great garden practices that can help prevent many soil borne diseases.

Early Blight

Hope it helps!
