780w led let's see how it goes.
As I've been increasing the light intensity it's been reflecting on the ec I've never seen anything like it.
I've had to raise the ec 3-4 times along with intensity and i can hardly satisfy the ec demand, I'm at 1.8ec and only just today seen double figures in the run off for the 1st time in a week (1.3ec up from 0.7/0.8 with 1.8ec going in 0.4 of that calmag.
1.8ec is a scary figure but I'm fucked off not knowing wtf is going on with the ec lowering in the run off, in future I'll know for sure to allow for intensity.
