New Grower ? Adding Nutrients

[idiopathic neuropathy]

Rookie/setting up 1st grow reading a ton of information...can't seem to find out nor figure out this question.

If i am using tap water and the ppm measures 100 ppm without nutes... If i am trying to attain 300 ppm. After adding nutes am I trying to reach 400 ppm or 300? Apologies for my stupidity.

Morning, welcome to AFN. 300 at first, some of that in the tap water are usable nutrients, I always go on the light side with baby plants untill they have a couple sets of healthy leaves.

Have you checked the pH of the water? are you growing in soil or hydro?

PH of water 6 and planned grow in coco

Just need to know if you add or subtract the amount that exists in the water so you can calculate correct amount of nutes....maybe i'm making a big deal out of nothing ----I

I always go by overall PPM, it keeps it simple. If the sprouts show any yellowing, up the PPM, if they show burn spots or curling leaves, cut the PPM down. 300 overall is where you want to be for seedlings, once they start pumping out branches you can go up to 500. I don't have any problems so far due to high ppm water, mine is over 100 PPM too.

Trouble is those tap water ppm aren't necessarily useful.
Unless your plants grow well in that water without nutes, then that water needs nutes.
My water is 210 ppm, and I always subtract that from actual ppm to get food ppm.
The feeding schedule from my nute maker calls for 50 ppm for seedlings, and I doubt they'd survive on tap water alone for very long.

But not subtracting tap water ppm will help keep you from over-feeding, the biggest source of trouble in hydro.
Many (most?) problems thought to be deficiencies are really over-feedings.

Roger that/thx

I have med-hard tap water. About 200 ppm on average. I take that 200 and add to it so that I get 200 more than the target I'm looking at getting with the nutes. I don't count the PPM of the tap water. I also recently switched to mixing my tap water 50/50 with RO water i buy by the big jug. So I am actually starting out with 100 ppm and add to that.

Are you adding supplemental calmag? Need that for coco.

yes on the calmag
