When peppers grow leaves, they need nitrogen. To do this, we make a weekly infusion of nettle or herbs.
When the pepper has bloomed, it needs phosphorus and potassium. Take 2 tbsp of fish flour per 8 liters watering can and water it. With a lack of phosphorus, the leaves turn purple.
If there is a lack of potassium, we make an infusion of ash, about 10l.150ml. a glass of ash and insist for a day, then water.
If the flowers fall off and the upper leaves are small, then fertilize with boric acid 1 tsp. per 10 liters of water.
