Looks rootbound to me. That pot is not big enough to support a plant that large. Just like the 'yellowing and red' plant on the other thread. IDENTICAL problem.
stinkyattic Reviewed by stinkyattic on . #@&$!!! N? or K? or? What is the deal with these 2 plants? they are 25 days into flower, and on one the lower leaves are starting to yellow...which might be a N def, but unsure since it has those black spots on them. On the other, the whole plant is a lighter green with purple stems, and also has some dying leaves- but looks like something completely different. First 2 pix are one, second 2 the other one.
