ok so here it goes
my starting water is roughly 16ppm
I called Chris @Hydroponic research
he told me to bump my starting ec to .3
and he told me to use
Botanicare Calmg @3ml per gal which brings me right to .3 ec
I then run 4g per gal
I am not seeing what you were showing which is def a
calmg def
the cal being the dark spots and the Mg being the lightning of the chlorophyll on the edges
what I am getting is a complete yellowing of the plant
if you look at your picture
the new leaves comming out that are slightly yellow before they grow out
well my entire plant is that color and the edges are dieing as well as the tips are turned down like as if they have N toxicity
but they dont
cant snap a picture right now because they are in lights out during the day
I do have a picture I can post when they just started
