It could be a number of things. Fill in the form and help will appear. I don't know if this is the right form, but it's the only one I cam across quickly and you can probably figure out what info is pertinent.

Strain of Mj?
Hydroponic or soil?
From seed or clone?
Age of plant in question?
What stage (Veg/Flower; how many days into)?
Medium (Soil, Rockwool, Hydroton etc.)?
Container/Pot size?
Have they been transplanted, if so how long ago?
If soil, composition ratios (peat moss, perilite, vermiculite etc.)?
Water runoff Ph?
Nutrients added?
Ratios of nutrients (N% P% K%)?
Feeding schedule?
When were they last fed/watered?
How are you determining when to feed/water (weight, wilting, etc.)?

Hey NorCal,

This response: Water runoff Ph? 8.2

That is BAD BAD BAD...

If your ladies were in this soil and had that much of a pH fluctation, well that could easily explain why the older leaves are showing slight yellowing, since she was probably feeding on herself for that period of time.

Other than the older leaves being yellow, she looks really good... keep it up and keep that pH in check!
