2,000+ ppm and thriving?

Gquebed · Apr 30, 2019

What i learned last run is that if your ppms or ec is high and you have a LOT of light you will run into probs.

So i figure people running high ppms without probs likely arent running enoug light...

And what happened you got burned? Last time I made that mistake I watched some pistils shrivel to brown on a few colas, this was about week 3. I had to move the light more than 2' above the canopy anything closer was burning..

No... thats just light burn.
I always keep my lights far enough away to avoid that. I'm talking about having lots of light per sq ft. The amount of light you have dictates how much nutes the plants use, to a certain degree. If you have lots then plants drink more but dont need high ppms. Plants use more nutes under lower light conditions. Need to find a balance. Lots of reading material on the subject...

I'm growing 2 Afghan Skunk plants and my ppms are running at 2600 I keep my LED at 14 inches above the canopy. I have very slight leaf burn in some tips but the girls are loving it.

I’m glad to find this thread. I’ve got chemdog auto in dwc and it has thrived at 2000 ppm. As I lowered the ppm it and 2 others all started showing burn symptoms. Or could I be mistaken underfed for burn? Edges are dry and crispy. I’ve read ppm should be around 1000 but none of my girls seem to like that amount. Using advanced nutes. I’m going back to my 2000+ ppm since it seems to work. My concern is my flush. You guys running high ppms, how do you flush?

My guy out here feeding 3000ppm in first weeks of flower……. ‍ The amount of Nutes/$ you are just throwing away is ridiculous.

The real question is are the high concentrations actually helping at all? Just because you can doesnt mean you should.

2,000+ ppm and thriving?
