Strongest EC Your PLANTS Have Ever Handled....?

[Buddernugs]

I’m growing black widow on the .5 ppm scail every time I pushed past 400 in first 6 weeks of veg from seed they stunted and got burnt tips.....now I’m in week 2 of 12:12 and anything past 600ppm and I see the same thing their extreamly light feeders... ps I’m in coco and I push 2.5-3gal of nute water every morning at 4am in their 5 gal pots so it’s basically a mini flush every day so I never have to worry about build up

It's a six year old thread and the only wisdom that can be gained from it is this excerpt from the OP's original post.

I stay on the cautious side and feel underfeeding is much less of a potential problem
than overfeeding.
