Someone will correct me if I'm wrong but set up your DWC with whatever base nutes you want.

Then the next day use your PPM meter and if it's lower, add water and some nutes at a slightly higher level, if it's higher, just add water. If your PPM and water level lowers it means your plants are eating the nutrients. If it raises that means the plant is drinking water.

If your using dwc than how would you feed everyday?
Most people ive seen just top up when necessary. And do cleanouts and water changes every couple weeks.
I would suggest using a good ppm tester and trying to keep everything consistent and u should be good.
Good luck sir

So lets say I start at a 125 one day and the next day it's a 95, I'd bump it up to 150ish and see what happens the next day and if the next day everything is consistent then I'd leave it for a week or two.

Does that sound about right toront?

Ya something like that exactly.
What i usually do i say i need 20 liters. I will mix up 30 with my desired nutes. Use the 20 i need then keep a bunch for topping up i know what im adding over the course of a week or two should be relatively close to the original. If the ppm is off i tinker with whats being currently used and try
to keep it as consistent as possible.

Im sure what i do isnt what everyone does but it seems to work for me.

Anyone know how much I should add per liter or per gallon if I don't have a PPM meter, and I'm just starting off? I'm only on day 2...

I would start off using 10-15% strength of the directions printed on your label.
U can increase it gradually and go by how your plants react and look.
Go on amazon or aliexpress and order yourself a ppm meter.
Its worth the investment so you can really dial it in.

Thanks everyone i will be picking up a ppm meter. How would a ppm meter tell me if they need to be fed? Sorry if that's a stupid question. Is there a certain number im looking to obtain each week? Im guessing it will gradually go up the further she gets? Also do i let my airstone run and make bubbles 24/7? Should my net pot actually sit in the water a little bit or just above it?

Make sure you pick up a pH meter to go with that ppm meter...

What kind of water are you using?

City
Well
RO
Filtered

What size container are you using? I always ran 2 air stones running non stop to really give oxygen to the root system

1 Go to the nutrient makers web site and download a feeding schedule

2 You don't need a ppm meter! (wait for it, more about this later)

3 You will need to dump and refill on a regular schedule for reasons we don't need to go into right now. Just believe us when we say to!!!

4 It's hydro - for gods sake add a Ca/Mg supplement!!!!! THIS IS LAW!

Try this method of DWC and you will remain trouble free

THE 33% Add Back DWC/hydro method

Mix up a batch of 100% strength nutrient's and pH to 6.0
Fill the res to you fill point - REMEBER how much this is!
When the res lowers and you need to add back to top off the res. Use a 33% nutrient solution to add back!
Mix one gallon of your feed mix and add 2 gallons of straight water - pH to 6.0 and top off the res.

Do this until the total amount of top offs would match the amount you used to fill the res at the start. Now dump it out and refill with fresh 100% solution and repeat the whole thing till you change to bloom feed and do the whole thing again till done.

You will NOT need a ppm meter to do this!
As the plant sits in the solution and you add back 100% solution - you will see the ppm's go up and up...This is a bad thing and is why others use a ppm meter and attempt to match the ppm's to the original ppm # at the start.....This too posses a problem of build up of "plant returned" chem's and why you NEED to dump and refill every so often.....

The 33% rule or method is fool proof and you don't NEED a ppm meter to do it!
You will save $ on nutrients too!

This is how you calculate if your underfeeding or feeding correctly

You're right Dr, you don't NEED a PPM meter but if you're just starting in hydro I'd recommend one.

Dr.Who i was told by the guy at my gardening supply store that i wouldnt need a ppm as well im going to assume this is why. He said something about this but they cant reallllly get into for legal reasons. I am only using House and Gardens Aqua Flakes A and B i was told i wouldnt need anything else. Im going to guess you think i should definitely use a Ca/Mg as well? Not sure if i can have the 33% mixed just sitting waiting to be used or should i only mix it up when i need it can the nutes just sit and chill in the watter until im ready to top off? My apologies again total noob in this field just want to get it right. Thanks for all the support!!

You can have a ppm meter...It will be nice for you to meter it at every top off and record the #'s for thought....

Yeah, you'll need a Ca/Mg !!! Gardening supply store man has head in ass! VERY, VERY few hydroponic nutrients come with the proper amounts of Ca and Mg in them.......H&G Aqua flakes is NOT one of them!

How big is your res? OR how many buckets will you be running? Well, you can make up oversize batch's of nutrient. Simply put an airstone from a line not used to go to your bucket(s) into it.......Oh, he didn't tell you you needed air pumped into your res either?
Yup gotta have that going on too...

Great info. I will def pick up a Ca/MG today. i have a 5 gallon dwc bucket setup. I will probably do the math and just put a third of the nutes in one gallon since i dont think ill need that much since its only one bucket if i cant do this correct me if im wrong please. The garden supply guy pretty much said the same as you about the ppm and not needing it he just left out the part of needing a CA/MG. thanks again for your time and knowledge definitely appreciated
