(Z)amnesia Autumn Auto’s

It's been an exciting week to say the least. I feel like i've just nearly avoided a total failure due to me completely not understanding the rules of the type of grow-medium i was using. The addition of GH bloom and micro to the feeding, and also keeping a tigher watch on my pH (working with 6.6 as an aim now, to make sure i dont kill my micro organisms in the soil) and on my TDS (1170 PPM as of now, plant seems to be happy with it) All that i'm trying to figure out for now is how to proceed in terms of nitrogen: i've tried adding no supplements that contain it because i feel like plant #1 is slightly curling down. Although it looks fairly healthy i feel like i might have given it too much nitrogen over the course of pre-flower (and maybe even before) So yeah steady as she goes! :) thanks for checking out my grow.
