PLEASE EXPLAIN PPM!

[Jewbilee]

I have been searching for a while and have found no answer, maybe someone here can help.
I am trying to figure out how pom works with my plants.
With all the additives I am trying to use/there are to use, I can never get to an optimal ppm range.
Does that optimal range not count additives and only counts base nutes?
Am I supposed to spread out the additives throughout the feedings?
Please help! My meter read 2100 tonight when I read the meter. I held off for a day to see if I could find an answer...
Thanks in advance...

Hey Buddy your PPM is part per million. Depending on what day your plant is on depends on how much you give. With autos we do 1/4 strength on nutes and half to full with cal/mag under led. That ppm is high. what are u using to measure with?What does the bottle say and what nutes do you use?

Most of the time I feed the 1/4 then go up until I get a little tip burn on the leaf tip then I know Im at max.

@DABaracuss
I am running AH calmag 5 ml/g AN connoisseur grow notes 16 ml/g A + 16 for b
(Shake it) Sugaree 4 ml/g
Nourish L 10 ml/g
Water is aerated for 24 hr at least, and has a starting ppm of 80-100

I finished my auto run two weeks ago. have 4 in the oven right now, photos, just switched last sunday...

I guess I need to restate my question.
Is there a maximum limit to the amount of base nutes a plant can absorb, or is it if the ppms are too high the plant won't be able to absorb anything?

Yes if the ppm is to high you will burn the plant from a too high concentration of nutrients.

Your ppm meter reads how well the nutrient solution conducts electricity, also called Electrical Conductivity or "EC."
Any salt, which most nutes are, added to water will increase the EC of the water, but non-salts like sugar won't.
We hydro growers HOPE that EC is directly correlated with ppm and nutrient strength, but it's just an approximation.
It turns out that typical ECs can be converted to PPMs for a common salt by multiplying by 500, but 700 is sometimes used outside US.

Bottom line:
Your ppm meter gives a crude idea of how strong the nutes are, for the ones that are salts, but gives no information about what the salts are, and can't measure non-salt nutes.
Use the whole ppm after additives, which you probably don't need anyway, except for calmag.

Just as you would be physically harmed by continuously over eating, so too are your plants.
Your PPMs are much too high.
