PPM question

Do you check ppm before or after adding you ph balance ?

Before. Just make sure to pH after adding nutes.

Never, apperently I suck.

Before and after any change!

I ph water first then let sit for about 1~3 days.when i need it I scoop out a couple gallons then add nutes.I go pretty high on ppm so doesnt usally need adjusting after.

Wtf?
Why would you ph first when nutes will change the ph?
Also, on occasion youll find that adding nutes will change the ph right to where you want it and you dont have add ph up or down.

So you ph then let it sit and go flat and give that to your plants? The water needs to be oxygenated before you use it? Or do you have a bubbler?
Also... see my other post... you guys are creating more work for yourselves...

I have the nutes I use down so well that I rarely even check ppm's or pH. I know how much nutes to measure out per gallon and how much pH down it takes to get the pH to 6.0.

Wtf?
I grow in soil and keep my water in a bucket with a small aquarium pump circulating the water. Gas exchange happens at the surface of water! I check ppm and ph after every step. Fill bucket, ph ppm check. Add ph down, ferts. Ph ppm check, ph down. Ph ppm check, usually spot on than it sits in the bucket until I need it.

Check PPM is the last thing I do, I also check pH, record both and then I water

I also check ph ppm and temp before I water.

I grow in soil and im exhausted even reading that let alone doing it

It takes two seconds to stick a probe in the water and 30 seconds to get a ph of water with a drip test.

It’s not that hard to keep everything in check


That’s 44 days from seed, lights go out at midnight tonight. I know it’s nothing special, I’ll just be happy if it’s actually a female.

Probes actually take longer than two seconds to read water or i might just be ready to commit

i let my tap water sit for 24 hours, i add nutes , i check ppm, then i ph the water before giving it to the plants.

ez peeezy

Great point! In the winter months I also check and often adjust the temperature as well

Cheers thanks for the input

I am a self-confessed lazy ass grower so I use RO water, which has no pH of it's own, and pH Perfect nutes so I just add a measured amount of nutes to the amount of water I need to feed my plants and pour it in. ProMix HP is my preferred media.

When doing DWC I check ppm and add small amounts of nutes to keep it up where I want it and have done whole grows without ever changing the nutes tho I try to do a change after the stretch when I feed Lucas Formula style.

After almost 20 years of steadily growing I've worked it out to the easiest way possible.

All I need now is self trimming and curing plants and I'll be a happy camper.

I see a lot of people spend much more time mixing nutes than I do. I guess I've been growing so long it's like tying my shoes. I don't even think about it really. But I use simple nutes and have been mixing them so long that I can get pretty close to knowing the actual ppm just by the color. I'm serious. But I've been using the same nutes for a decade.
