The plants are looking much better this week. I'm going to hold off on nutrients probably until next week. They seem to be fully recovered and doing well. Plant 2 is showing pre-flower at the end of this week.
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!!!
