Help! What is happening?

[Smanto]

This is happening to all of my mother plants and clones. Once a plant goes to veg/flower she grows out of it. All of the leaves come from inside and underneath the plant. Except the clones have it on the newer growth. Any ideas?

Phosphorus deficiency, probably from ph fluctuation.
