It's a work in progress for me mate. I don't think the LEDs help but not sure it's the cause. I have a NL auto in veg which I'm PH and going to pick up a bottle of Biobizz Calmag since my water is soft.
My thinking at the minute is my water is throwing out the pH. So it buffers for a few weeks and then looses it's ability. Plants grow rapidly, not enough Calmag in my organic grows and then shit hits the fan. Just a theory ATM but here's hoping.
Not getting any younger and I still have my eye on POTM ;-)
