Here's a question that I think I know the answer too. But I am not 100%.
DWC, do you add your starting measurments; TDS, ect. to your tageted levels or subtract or just ignor them?

The starting tds of your water is included in your total tds of your nutrient solution. For example if your water is 120ppm starting and you want to mix nutrients to 500ppm then you can only add 380ppm of actual nutrients. This is why some people prefer to use ro water in hydro. I adjust my feed according to what my plants look like rather than measuring ec and all that though. A lot of factors in the environment contribute to how high or low of a nutrient dose your plants will want.

Yes they are in! Thats why a lot of growers start using osmose water , the PPM or EC can now be taken by nutrients the plant is asking for.
Happy growing!

if what you add is at same dose (ml/l or g/l etc) then it stays the same. "TDS"
it is a weighted average... add the same concentration, it stays the same concentration.

Nutrient lockout? [first grow]My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before.
Is it nutrient lockout? Or just deficient?

PH measuring for Organic GrowersIf I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.Other. General questions

Advanced nutrients in soil runoffAdvanced nutrients in soil.
Hey, so I'm using advice nutrients line (sensi) in biobizz soil (light and all mix 50/50.) Anyway my runoff is always 5.8PH I'm guessing this is due to the PH perfect technology. My soil is buffered to 6.2PH and I always PH up to 6.3/6.4...Feeding. Other
