4 plants are 16 inches tall, 1 plant is a little behind at 13 inches. I'll probably flip to flowering at week 7.
Impressions about plant
Super happy with their progress. Watered with 5 Millitres of cal-mag at 6.4 ph, ppms were 240 to 255. Each plant took 1 1/2 gallons of rain water filtered 2 times.
