I just bought a PPM meter to up my game… this has probably been answered a million times in numerous threads, buuut I didn’t search, so let’s start fresh.
Who can give me a crash course on the basics of measuring the ppm of nutrients? My tap water measures in at 30 ppm and 7.0 ph.
Is there a process to follow? Like measure the ppm after each nutrient is added? Or a “goal” level for the final mix? I have zero…ZEEEROO idea or knowledge on this subject so any info is appreciated
ppm/ec/uS all it is the measurement of the conductivity of water, saying that different things in said water will be more or less conductive than one another, so will different nutrients brands type parts ect
but as recommended start with a value and level you know then work from there
Where can I find out what I should be aiming for…I measured existing nute mix at 260 ppm (seedling feed). Is there charts i need to follow, Google links I should read? Typically I go half recommended dose for seedlings and back dose for anything else .
Basically… im down to go into a Google worm hole of info I probably don’t need, I just need to know which way to go first lol
Should I measure say, 500ml of each specific nutrient to know its ppm, and rocket appliance equation that into the water for a diluted goal, or am I way off track
if using multipart nutrients you would measure after mixing in each part , if its a one part well just the final value. that and knowing your starting value before nutrients is handy but a tap of 30ppm is nothing so you can more or less disregard it
260 is fine for veg depending the plants needs I feed on average 450 my tap is 260 mid veg 600 veg / flower 800/1000 depending how they feel do 2 feeds then a semi flush straight water then 2 more feeds
consider though that is with your brand/type of nutrients and your water, as a 600ppm of miracle grow vs a 600ppm of maxi gro is two completely different things and you should only compare values if the make up of the nutrients are the exactly the same.
