Has anyone else experienced this? I’m having some nutrient burn issues since upgrading my lighting. I’ve been reducing my EC and I’m not seeing any deficiencies, but it’s still surprising that the plants won’t tolerate levels that they were fine with previously. Plus I think I feed a lot less than others (my EC is usually .7-1.0 if I go above 1.2 i get problems)

But of course!
If you feed plants that aren’t eating/growing, the salts will accumulate in your grow-media.
I hardly ever feed above 0.8 EC in my veg room which is under low-intensity fluorescent lights (slow growth).
I’m having the opposite experience. I have high intensity 900watts (actual) + of high efficiency LEDs and am finding I have to also feed less.

Is growth slowed by another factor like temperature?
When I see burnt tips in my veg room, I’ll mix in an extra water-only feeding per week.

Yeah @Scissor-Hanz , growth is slow when I use a quite cold/damp cab for vegging/cuttings under CFL’s, the growth rate slows quite a bit, but enables me to slow down plants that I’m not wanting/needing til i finish flowering etc…
Just my experience bud… Happy growing

high temps/light intensity could cause the plants to transpire more causing them to drink more and intake more nutrients

or causing the media to dry out quicker through evaporation which also increases salt levels
