After three days, I see obvious changes in ladies' behavior. The leaves grow slower, and buds are growing bigger. I sprayed everything with Maxicorp 2ml x 0,5 l. I like it, and ladies seem to like it, too.
Today, I noticed a weird leaf on my WW, it looks totally wrong... I am sorry for bad pictures, took them with my mobile cam.
P.S. Widow in coco is growing as big as the box inside.
