Should a healthy mother produce yellow leaves?

[mortyb]

Is it normal for a healthy mother to produce a few yellow leaves? I would assume the oldest leaves should eventually reach maturity & start dying off even if the plant isn't put into flower (natural cycle for leaves to start dying).

Does anybody know if this is normal?

A mother plant will eventually get rootbound. Random leaf die off is normal for rootbound plants. If you wish to prevent it, you need to regularly trim the plant, or re pot it in to something bigger.

Or prune the roots (yup, pull it from pot, cut an inch off the mass and replace with fresh media.)
Add micho's and the vigour will return.

Trimming the roots without trimming the foliage will give you even more old leaf die off.

The plant wants to keep growing, but is hampered in doing so due to the inability to create new roots. The current roots are needed to provide the plant with needed nutrients and water. The die off occurs when the plant pulls resources from the old growth, and puts it in to the new growth.

So if you just cut the roots, without removing any foliage you will see extreme leaf die off of old growth. And lots of new growth.

Removing roots from a plant is extreme. It doesnt give you any benefit over just removing old growth, and its a lot more stressful to the plant. I wouldn't suggest it over just trimming the plant.
