Data was from run off.Having trouble with nute burn on my vegging girls. So I just got a TDS PPM meter. Its showing 2310 ppm. I'm flushing it now. What is the recommended PPM for plants in veg phase?

Strain dependent of course but here is a good resource:
https://www.rollitup.org/t/reliable-ppm-chart-for-marijuana.200589/
Seedlings, Early Sprouts 100 to 250
Early Vegging 300 to 400
Full Vegetation 450 to 700
Early Blooming 750 to 950
Full Mature Blooms 1000 to 1600
If you are watering frequently but in small amounts with little or no run-off you will start to build up and that could be the reason for the high PPM's.
How often are you watering? How often are you feeding? How much run-off (if any) on each watering?
How large are you pots? How old are the girls?
I would do an aggressive watering ASAP with only PH'd water for starters.

When it feels light or every other day. There in 3 gallon pots the ones that encourage air pruning and their 5 wks from germination.

Boiling 5 gallons now to dechlorinate ASAP and cool. PPM were probably lower than what I mentioned. I have nute burn but also took reading form bottom plate that has residue.

Did you raise the light for the picture or is that how far away the light is from the plants? Your plants are incredibly tight!!

Thats how far away I keep, just got Solar Flare, Killed earlier plants last time when I put LED to close. So I just watch for stretching and moving cautiously. 16 in for blooming 20 to 36 for veg are the recommendations.

220 watt. Got tired of playing with cheaper LEDs and just went for it. So light won't be a problem just my lack of experience, looking at getting another 110 watt Solar Flare for my tent thats arriving next week for a 3ft by 2ft bloom area, these are the bomb you can see the different colors on the plant awesome

I never get tired of seeing the color of an LED. Have yet to see one in person. So for a 3x2 tent you will be using 330 watts?220 watt. Got tired of playing with cheaper LEDs and just went for it.

Well my 220 give high bloom intensity for a 2x2 area at 16 inches. Since it's high bloom intensity I'm contemplating raising it just a bit to cover whatever maybe 18 it should still give great results as far as light goes. A 110 gives 1.5 x1.5 at same distance.

They are 220 was 440, a 110 is about 250. California Lightworks could not find one bad review.
