She #9, is showing possible signs of mild S def (light purple striping on main stem/trunk) I did bump the ec this week from 1.5 to 1.65. No other symptoms so if plants do not deteriorate in health, maybe genetics. Day 62 pH 6.2 ec 1.60 temp 65.8F. Will be changing res in 2 days. Day 63 pH 6.2 ec 1.59 temp 65F.
