Although, if this is week 7 from seed (I'm not real clear as to what you mean, "week 7..."), then you definitely need to up her nitro intake. Too, I do see a bit of purpling in the stem, which may be a symptom of a mag deficiency. However, some strains do carry the purpling, yet I would still add 1 teaspoon of Epsom Salt to one gallon of Ph'd water to get her healthy again.

*Note:* By giving her Epsom Salts, the purpling of the stems will not completely go away; however; new growth will be greatly improved and her leaf tips will stop pointing down and begin to straighten back out.
jbby81 Reviewed by jbby81 on . Week 7 yellowing...normal? so i turned my lights to 12/12 oct 1, and the plant was doing really well up until the last week the lower leaves have been drooping and yellowing. the big fan leaves are still soft and arent falling off...yet atleast. I know i have a bug problem already haha i'm in a frat and its dirty as fuck i've been trying my best haha. But does it lookk like yellowing from the bugs over time? or is it normal nitrogen deficiency? thanks Rating: 5
