Is this nute burn?

vecrex · Feb 28, 2013

Hey all. Week 5 of an 8 week GDP strain. A few plants are browning at the top and I wanted confirmation from those who know better whether or not this is nute burn. Any help appreciated.

1000w HPS
5.8ph RO
Hydro in Grodan
1000-1200 ppm mix usually
Micro, Bloom, Karma, Bloom pro, low dose gravity, sweet.

PPM is far too high.

sick34 looks like N toxicity, early stages unless the lighting was goofy when you shot that pic

I've run this strain as high as 1500 before though. I do admit to not pure water flushing this time around and simply lowering the ppm a few times to around 500. I've always questioned this mix however, since I was turned on to it. Maybe it's time to cut down on my ingredients.

I've just flushed with pure 6.0ph water. Anything else I should do to get things moving again?
