Day 44: Both plants are doing well. Plant 1 is 31 inches tall. Plant 2 is 49 inches tall.
Day 45: Plant 2 is starting to get a bit frosty.
Day 47: Plant 1 doesn't seem to be doing much. I think all the early problems are the cause. Plant 2 is doing well.
Day 48: Plants are looking good. No pictures.
Day 49: Plant 1 is starting to stretch, and seems to be recovering. She is now 39 inches tall. Plant 2 continues to stack on buds. She is 53 inches tall.
Looks like a magnesium deficiency to me. Some of the pictures from last week it looks like there is some interveinal yellowing and the deficiency has progressed. Epsom salts will help fix the issue. Happy growing!!!
