Листья Желтеют, хотя цвести ещё 30 дней

Plant is lacking nitrogen uptake so its taking it from the leaves. Feed the the plant or plants a small amount nitrogen next feeding. Plants in this phases don't need much.

No, not normal. A picture of the whole plant would be helpful so we can see where the problem is occurring on the plant. Your diary only lists a brand name of fertilizer but I don't see where you say what you are using. What nutrient are you using and in what quantity?
