I have a question? I am in the middle of my third auto grow and I have yet to gain height in my plants. The tallest Ive grown is 22 inches tall. It was an Amnesia haze and it was rated between 24 an 32 inches tall. the rest averaged about 16 inches. I have an Auto JH that is at 20 inches after 7 1/2 weeks. The buds are immature so Im gonna let it go for 12 weeks instead of ten. I also have a blueberry blisds that is also 7 1/2 weeks old and has great looking buds on it but is only 16 inches tall. I have checked for pests and deficiencies there are none that I can see. I grow in promix and use foxfarms nutes. They are really awesome looking plants nice and bushy and green Just not gaining any height. I sure could use some advice on what Im doing wrong. Oh yeah The pH is between 6.4 and 6.8 Thanks ahead of time.
