Thought it was N def at first but it’s even worse now.
EC was 1.0 but upped base nutes to 1.2 to see if they were just hungry. Doesn’t look like it was that.
PH is 5.0 tonight which I need to up to 5.5 which I let swing to around 6/6.2
Flood and drain setup but flood for 2 hours as I’ve added airstones in each pot so it’s more like DWC.
I thought tonight could it be light bleaching as the 600MH is quite low at around 14”?
Roots look really healthy.
Any ideas thoughts welcome!
