By the beginning of the 10th week, the towers have already formed enough, and now they continue to widen. The upward growth is about 4-5 millimeters (approximately 0.18 inches) per day. Based on the planned 4 weeks and maintaining the same rates of vertical growth, they should grow another 140 millimeters upwards (about 5.51 inches), and my grow box allows for this.

The vertical growth of the tallest cola has almost stopped between 75 and 76 centimeters. However, the other colas continue to grow taller. And all continue to thicken and widen. It's interesting to see how thick they can grow.
The scheme with equal low doses of 6 fertilizers has shown that it does not burn the tips of new leaves and allows the girls to grow, so I will stop at it for now.
According to the plan, I suppose a couple more weeks of growth.
However, for precise diagnostics, I lack an electronic microscope. A regular consumer one does not satisfy with its quality.
