Nectar for the gods in sunshine mix advance #4

I have been growing six plants in sunshine mix advance #4. I have been feeding the girls nectar for the gods nutrients. I just switched to flower last Sunday and am experiencing multiple deficiencies on the lower leaves. I am wondering whether or no I have been feeding the girls nectar for the gods nutrients. I just switched to flower last Sunday and am experiencing multiple deficiencies on the lower leaves. I am wondering what may be causing this? What are your personal experiences with using nectar in a Hydro drain to waste set up?

Wow, first negative thing I've heard regarding Nectar For The Gods! I only use two of their products (Bloom Khaos, and their Liquid Bonemeal in flush), so I'm afraid i can't help.

Is new growth suffering also?

Only the older and lower growth. I don't think the line is causing the issues. I think it is the fact that this is my first grow.
