Having put my three girls into 12/12 just around 2 weeks ago, I have noticed that quiet a few of the older and lower leaves are turning yellow, and the leaf stems are turning purple, is this simply a nitrogen deficiency perfaps due to build of salts in soil, or as a result of the plants chemistry changing, I know these lower older leaves act a N resevoirs so could it just be that the plant is redistributing its Nitrogen? Or could it be anything else? Perhaps this is normal!! Any comments would be welcomed, especially if you have an answer.

Thanks in advance
