Lockout?

Agreed, somehow this thread became about TDS vs PPM, etc.

The basic message is: leave the water out for a day or so, and don't add calcium.

There is no TDS vs PPM. There lies the problem. They're both derived from a calculation made based off the EC reading (on most cheap EC pens etc). True TDS is more complicated than just EC formula conversion all these pricks are doing.

EC is the base reading most of the world uses lol. I don't know why this is so hard to grasp. You all just hold on to ppm like it means something or had more important value than EC when ppm is just some calculation/formula some jackass made up to mean the exact same thing the EC reading says in a reverse calculation/formula.

If anything go by a different metric unit of measurement, and instead of using EC, use CF or mS/cm or if you're super anal about accuracy of your feed and the changes in the water, convert to μS/cm

This is all metric system folks. Like 10mm = 1cm. Kilometers, decameters, decimeters, cm, mm, and on and on from 0.00000000000000000000000001 to 100000000000000000000000000 and beyond

You're just converting a SUPER SIMPLE SIMON measurement system to imperial ppm gibberish. (Imperial actually has a place in measurement though unlike this ppm, ie fractions and decimals)

Like wtf folks?

Stop buying cheap ass EC meters if you want accuracy. The ppm conversion is just a gimmick.

Again, as for his plants, I have no idea if it's too much cal. Too much phos and potassium also lock out Calcium. Test the damn output EC in the water. Or again, test in CF which for every 100 CF = 1.0 EC

So if you have a reading of 69 CF you have 0.69 EC

Also test the output PH

Honestly, I don't care if anyone doesn't learn from all this. It's like beating a dead horse at this point.

Simple Simon shit
His feed charts are all done in EC ffs lmao cmonnmmmm maaaann.

People will argue about the most trivial nonsense.. You are making it way harder than it needs to be for the OP.. I don't care how you measure. Helping this guy isn't as hard as your making it. I digress as its just dumb to continue. I wish the best outcome for the OP.

It isnt trivial and in fact quite significant in how ppl understand how this all works. It does matter how you measure. You yourself said you don't like to wing your grows.

That's what you're doing with ppm magic fairy tale #'s derived from EC.

Just pure fantasy.

The PPM debate is very important. Growing weed 101 stuff. Measuring a tank in a standardised way. It's hard to move forward on a feed topic, if you can't talk about how much you are using.
If this topic is confusing people, or making them bury their heads, then they know they don't understand their meters, and should use EC. We all know what EC is. It's a single standard of measurement, that everybody is using. Starting from the upper tier, and slowly getting down to the ill advised newbies.

This is off topic enough to not be confusing the real issue imo. As I don't see a feed problem here. The OP has doubled his light with a switch from HPS to LED. Everything else remains the same. Except location, which is across the palace courtyard.


Edit: I should add I have no problem with Hammer using his meter how he does. It's a valid workaround the fact his meters resolution is too low on the EC scale. I would likely do the same, but wouldn't ever give out the PPM number. Only EC can be shared between all. PPM = Piss Poor Measurement.
