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.

m0useanswered grow question 3y ago
are you asking if you add up numbers to make your ec/ppm quota?
example:
reservoir has 300ppm
top up feed has 400ppm
and together they make 700ppm your target range. and you want to know if this is how you do it?
or if you just add in 700pm
is that the question?

PH Levels - Watering vs RunoffAfter my first transplant, I saturated the grow medium and did a PH test on the runoff. I'm watering with un-PH'd aerated tap water which is naturally at 6.5. The runoff water is coming in at 5.5. Should I alter the PH I'm watering with so the runoff meets my PH target?Week 1

Are we Twins? would we make a good couple? who are we lol?Essentially is the same nutrient correct? From my understanding, a PK booster is usually thrown in the middle of the flower cycle for about 2 - 3 wks. I've also noticed it rarely cut out. Can/would you mix the product lines? what weight differences have you seen with use?

PPM in DWC hydro systemHello,
It's my fist time with hydro and my girl are doing very well, she is an Auto on second week of bloom and the PPM are around 1000 of Remo Nutrients.
She are drinking 1L by day and the PPM dropped too.
Must I put water with ferts or just clean water? If with ferts how much?

EC going up daily during the day - Hydro recirculating systemWould anyone have an idea why the ec in my tank goes up every day of the plant, like 7 or 8 hours after the lights are on ? Evaporation ? The plants eat more at this time of the day ? Overfeeding ? Got a small 20L tank and a tight space. Thx !

Ec rising in hydro (6th week flowering - closed circuit tank and drip)At the end of every day, EC rises by 0.2 at least. Starts at 1.60 and then in their evening it goes up to 1.83 ! So I have to add water (2L) in order to go down. Does it have to do with the fact they had overfeeding, toxicities and deficiency so they don't feed well ?

PPM. 6/6,5 PH waterings or too frequent waterings?I just had a long ass session in my tent, because of increasingly higher PPM. Coco in 10gal, is every day irrigation too much? Should be said that the pot is nowhere near dry after 24hrs. Or my initial idea, 6,5 PH every other watering being too high leading to lockout? ThankssWeek 6

When to introduce nutrients to coco / perlite and how to water seedling?Hi!! I am doing my first ever grow. When should I introduce nutrients to my plants in coco? They have just sprouted and I was only giving them some water with H2O2 at a PH of 6.2.
For a seedling, do I need to water until I get runoff?
Thank you!

Adding Bloom NutesI'm thinking about adding either Overdrive or Big Bud to the nutrient list so my question is two fold. I think I have probably 4-5 more weeks of flowering is it worth it to add more nutes now? I would also appreciate anyone's opinion on using these independently vs together.Week 7

Coco grow, runoff EC levels LOWER than input levels. Hungry plants or something more sinister?Since getting a better light, runoff EC has been dropping steadily, and is now LOWER than input (~ -75 micros below). Not just an anomaly, this has been every feed for 3 days and is predictable. Could my plants be asking for more food in response to the growth from the new light?Week 4
