High EC with CO2 & Max Ppfd

Is 4000ppm to high of nutrient solution levels in reservoir. Running 5 gal DWC Jokerz Cultivar. CO2 @ 1500 ppm ppfd at 2000 @ canopy with under canopy lighting. Using GH armor silica 2.5 ml/ gal, cal magic at 3 ml/ gal, Floralicious Plus 1 ml/gal, Botanicare hydroguard 2 ml/ gal, RAW NPK enzymes at 1/16 tsp/ gal, Floramicro 8 ml/ gal, FloraGrow 4 ml/ gal, Florabloom 15 ml/ gal, ripen 4 ml/ gal, dry koolbloom, 1/2 tsp/ gal.IMG_0410.jpeg

First, convert to EC; that makes it easier for people to understand, since there are several different conversions between them.

Second, it sounds way too high. I don't know anyone who runs higher than EC 3.0 and even then only for a short time in peak bloom.

It’s actually 2500 ppm not 4000 like I mentioned

it seems extremely high but your plant looks like it handles it well, Question is if you get the same or better result running a lower EC.
Nutrient uptake aint just about the EC. It is entangled with VPD and frequency of irrigation. You can push a plant more when envoirment and irrigation is on point, and less when not. Lower temps in general usually means you have to lower the EC.

Thanks for the info

2500 PPM is about 5.0 EC
Very high, but if you really push 2000 ppfd and use CO2 that EC is reasonable.
But... Look at your plants...
To me they are over N and burning slightly
The burn is not increasing fast because most of it goes to budding at those rates of transpiration
I've gotta say your plants are wicked crazy stump trees !
Don't listen to people who tell you to go below 2.0
Those people never pushed plants to their limits which is what you are doing with your turbo like environment
I say lower to about 3.0-3.5 EC and go from there keep checking your plants to see if they balance out the green in their leaves and the burn is not progressing.
