Alternate between moisture level 2 and 4. 2 - MEDIUM: Soil is light brown in color, no water can be extracted form soil, and soil will crumble apart. 4 - WET: Soil is dark brown but not shiny, no free water is seen at the surface of the soil, when pressed or squeezed water drips easily, and trays are heavy with a visible bend in the middle. Pinching: No Plant growth regulators (PGRs): Spray with Bonzi ® at 1–5 ppm if hypocotyl stretch is observed or if environmental conditions are such that hypocotyl stretch is likely. Apply at the 1 to 2 leaf stage. Use lower rates in Northern
