n def or p/k tox?

I'm about 3 weeks from harvest and yesterday switched my plants to week 9 of the fox farm feeding schedule and fed at 1/2 strength. I know the plants will soon show signs of n def and that is natural but as I so recently cut the n out of nutes im not so sure this is my problem. 4 of my 5 strains had lower leaves that looked like the pictures. The 4 plants that had those leaves also have multiple tops and were trained into bushes.

Those leaves weren't receiving enough light so the plant dropped them if indeed they are bushes. Show me a picture of the whole plant if you can.

That's exactly the problem. Not enough light in the lower growth so the plant will use what it can from it and drop it. Its a normal process through a plants life . your plants look beautiful don't change a thing

Never cut N out of your nutes, at any point in time. It may be natural for pot forums, but it is not good horticulture.

IOW, why do you want to induce yellowing and premature leaf necrosis when its leaves that drive bud production? Does that really make sense?

THINK. Don't be persuaded by vendors and misguided or popular forum thought.

I'm sure the soil has lots of n already in it as I've been feeding it rather heavy. The only leaves turning yellow are on the very bottom of the plants where no light reaches. They are still receiving some just a very small amount compared to previous weeks. Is it best to flush one or two weeks in soil?

Flushing is a myth, more forum crap.

N still left? That is a feeling not a fact.
