Indeedi think we just need to get rid of the ppm measurement and run off ec.
Wow looks off bet the bud tasted bad and burnt black. /sThis really has nothing to do with EC, but I thought it was interesting. This was from painters tape covering a branch. I’ve seen the debate that LEDs “bleach” branches purple vs LEDs cause a deficiency that turns the branches purple.

Definitely a localized deficiency.This really has nothing to do with EC, but I thought it was interesting. This was from painters tape covering a branch. I’ve seen the debate that LEDs “bleach” branches purple vs LEDs cause a deficiency that turns the branches purple.

In your previous example, the plant was basically shutting itself down due to semi-toxic levels of salts. That doesn't get you the "same results" at the end of the day. It gets you a less healthy plant, albeit perhaps productive nonetheless.Yes but within levels roots regulate all uptake in many ways, it was just to answer why one can run lower or higher and get the same results not to say overfeeding will work well.
It seemed that was the case here, some run lower some higher.
To play devil's advocate, it could be true due to higher photon output with LED vs HPS of the same wattage, therefore the plant could potentially use a higher EC, if all other factors were also already at optimum.This simply isn't true.
Most people can't taste subtle differences in general at all. A small % of the population can smell/taste much better than everyone else. People with big noses.But the real question is, can someone taste the difference between 2ec and 3ec?
Be a cool thing to set up some friends and do a blind taste test.
Hahahaha. Ive always wondered if im a super taster, i can usually taste things others dont notice.Most people can't taste subtle differences in general at all. A small % of the population can smell/taste much better than everyone else. People with big noses.
This reminded me. I ordered a syringe to pull solution out of my rockwool to check the EC. The mailman just dropped it off about an hour ago, so I'll try it this evening. Thanks for the recommendation. (I'm pretty sure it was you, although I may be mistaken.)In your previous example, the plant was basically shutting itself down due to semi-toxic levels of salts. That doesn't get you the "same results" at the end of the day. It gets you a less healthy plant, albeit perhaps productive nonetheless.
He's indicated that he needs to run more than DOUBLE the EC under LED. EC is exponential so 1.0 EC - 1.4 EC to 3.0 EC under LED wouldn't make up for any increase in photon output. He didn't say it was runs from the same clone, so if it wasn't the whole argument is invalid anyways.To play devil's advocate, it could be true due to higher photon output with LED vs HPS of the same wattage, therefore the plant could potentially use a higher EC, if all other factors were also already at optimum.
Not really, below semi toxic it altered roots to accept more so the opposite of what your saying.In your previous example, the plant was basically shutting itself down due to semi-toxic levels of salts. That doesn't get you the "same results" at the end of the day. It gets you a less healthy plant, albeit perhaps productive nonetheless.
Maximum EC is dependent on multiple factors. In a high transpiration system 2.4 EC could burn the plants up and 1.2 EC could lead to deficiencies. It's also dependant on PPFD and CO2 supplementation.I felt the main question was
- How high ec can we go and how is one at 1.2ec achieving the same as another at 2.4ec.
No, EC is linear. E.g. add double the salt, the EC doublesHe's indicated that he needs to run more than DOUBLE the EC under LED.

it's also that HPS increases leaf temps so they transpire moreTo play devil's advocate, it could be true due to higher photon output with LED vs HPS of the same wattage, therefore the plant could potentially use a higher EC, if all other factors were also already at optimum.
Thanks for the correction, as @Kassiopeija pointed out it was pH that I was thinking of.No, EC is linear. E.g. add double the salt, the EC doubles
Think your deliberately missing my point whilst I'm agreeing with yours.Maximum EC is dependent on multiple factors. In a high transpiration system 2.4 EC could burn the plants up and 1.2 EC could lead to deficiencies. It's also dependant on PPFD and CO2 supplementation.
You can't just say a plants max EC is "x" without quantifying the additional required parameters.
You're right, that is too extreme. I didn't look at the details. I could see going from 1.4 EC to 2.0 EC though.He's indicated that he needs to run more than DOUBLE the EC under LED. EC is exponential so 1.0 EC - 1.4 EC to 3.0 EC under LED wouldn't make up for any increase in photon output.
