they say in the book that ther sapose to turn yellow meaning ther using all ther energy to grow roots
Bumping this one up
I noticed some yellowing on my clones today - looked like an iron deficiency - it's been a week since taking cuttings - and the ones that had begun flowering are the most noticeable (yellowing).
But they are basically feeding on themselves until they establish a root system.
But as long as the new growth looks green, they should pull through.
