Symptoms of pH problems: leaves are fully yellow or have yellow or brown spots.
Causes of pH problems: the water in your grow tank is too acidic or basic to enable the plant to grow successfully.
Take a photo of your plant leaves of concern and post a ticket for a plant consult, or Report at pH Problem Issue in the mobile app. The plant health group will adjust your growth recipe. They may also suggest you run a Water Tank cycle after the update.
Plant Maintenance: If the pH Problem is caught early, your plant leaves will recover. If however, any leaves have fully yellowed or browned, carefully snip them off as they will not turn green again and could shade your remaining healthy leaves.
