New growth is post-transplant growth and after I switched plants to the organic soil mix. This new growth is greener than the previous mix and relatively free of Mag deficiency. Old stressed growth as evidenced by red petioles is the stage when the plants were growing in Coco perlite mix.
6 Weeks to go. Lots of chopping will be required to keep them contained. Wishing for an extra 1000 sq ft or so. ;-)
