Organic gowing, help diagnosing deficiency/excess

[t-bot]

Hi All,

I started an organic grow and all was fine till the older leaves started to turn orange/rust in color. This started with spots on the leaves and then some necrosis as the leaf part that turned orange/rust dries off. I looked a few places for deficiency/excess charts but can't seem to pinpoint the exact cause so I'm asking for help. Let me know what you think or if you encountered these issues before.

Cheers!

Post in the "infirmary" but she doesn't look well. There is a sheet to complete which asks for temp, nutrients, etc etc
