Fertilizer checks before changing a blend
Start with label and water facts
Read the guaranteed analysis, dilution notes and mixing warnings before using a product. Then compare the label with source-water EC, pH, alkalinity, crop stage, substrate, irrigation method and salinity risk. UAE heat and salty water can make a recipe stressful even when the numbers look normal.
When symptoms appear
Yellow leaves, burnt tips or slow growth are not always fertilizer problems. Check heat stress, waterlogging, root health, pests, drainage and irrigation uniformity before increasing nutrients. Keep a record of the product grade, dose, water reading, date and plant response so the next adjustment is measured.
