Bag Seed from Meds

This is were some of my dates may be off a bit but ill do my best to show the growth time line. Had what i think was a shortage of cal/mag. So i added more next feeding. Some stems were purple and other leafs were rusty looking on the bottom half of plant. Top new growth was looking great. I flushed with about 30 gallons untill water turned clear & cleaned her up before flipping to 12/12 flower stage.
