Id raise light to 24” minDWC hydroton
Ppm is around 800-900 it’s been a min since I check it. But ph after nutrient added is 6.0
Ok so I went a head and read through it a couple times, I kept getting interrupted with phone calls so it took me a bit to digest it all. First I wanna say, that is one hell of a informative piece there. I’ve done some reading on ph and that one covered more ground than any one that I could find. Second from what i gathered about from that as far what concerns my current situation is somewhere in here.Id raise light to 24” min
Drop your ppm to 500-600
Ph down to 5.8 and let it drift up to 6.2
You want a PH drift of around 0.2 per day.
Read this in PH to help you understand how and if you have any questions on it just ask.
Marijuana pH Levels for Growing Weed: A Basic Explanation
OK I'm going to do my best to explain PH since its something that is for the most part greatly misunderstood and can be confusing to new growers and even experienced growers alike. This will explain why we need both ppm and PH meters to give us informed information about PH This will be a...www.thcfarmer.com
Yup your on the right track. If you copy paste or link your water report (suggest removing identifying information) i can interpret it for you if you like.Ok so I went a head and read through it a couple times, I kept getting interrupted with phone calls so it took me a bit to digest it all.

-In hydro the ideal ppm of carbonate/bicarbonate sources to provide an adequate buffer will be 50-100ppm with 75ppm being the target. Less than this and PH may swing to fast and be unstable, more and it will not drift enough and will require too much acid that could affect nutrient ratio's negatively depending on the acid used. By adding alkalinity and then acid we provide a more stable PH because adding more of either will have less impact on the overall ratio of acidic to basic elements-
I use tap water which is close 8.0 in ph. And about 250ppm. now I’ve Googleed the make up and couldn’t find a decent one that isn’t super confusing or misleading due to them trying to sell me something. I’ll do deeper dive tonight, but since I’m using the tap Im definitely using quite a bit of down which is not great from what I read, so Should I be using RO and if so should I be getting the RO water to 75ppm, then adding my nutrients and lastly checking my ph and adjusting accordingly after I’ve done all that an.
aaaaand lastly I think I should do a good flush before I do any of those things so I know i don’t have any leftover crap or build up of any sorts. And i on the right track yet?
I’ll try and get that report cause I definitely would like to have that info.Yup your on the right track. If you copy paste or link your water report (suggest removing identifying information) i can interpret it for you if you like.
Even at 250ppm it may be usable but ideally we all start with RO. But by no means is that always needed
Yeah GH PH down is mostly phosphoric acidOk got it and I do all of that before adding to my res. Can it be the ph down from general hydro or does it have to phosphoric acid.
Definitely gonna get that thing this weekend I hadn’t done a good search online just shopped around at lowes definitely beats there’s that is priced out at like 2 bills! I appreciate that
When/if we use tap water, we will let it sit for 24 hours in 5g buckets to allow the chlorine to evaporate out of the water and, only then, do we start creating any solutions with it.Ok so I went a head and read through it a couple times, I kept getting interrupted with phone calls so it took me a bit to digest it all.

While i agree mist water supplies are chloramine now and that wont off gas like chlorine and even aerated will last weeks. Of your worried about it then 1 gram of ascorbic acid will neutralize 1ppm of either chlorine or chloramine in 100 gallons of water.When/if we use tap water, we will let it sit for 24 hours in 5g buckets to allow the chlorine to evaporate out of the water and, only then, do we start creating any solutions with it.
We almost always use RO water, and if you're going to invest time & energy into the more advanced chemestry, you should as well so you can strictly manage ppm in the solution.
What are the byproducts and other reactions of mixing ascorbic acid with chlorine or chloramine? General Hydro pH Down is using phospheric acid... how do those 2 acids react with one another?While i agree mist water supplies are chloramine now and that wont off gas like chlorine and even aerated will last weeks.

Most municipalities are around 1ppm of either and the max allowed in drinking water is 4ppm by then it will reek of chlorine.
Ino bothing to worry about unless you uare using it to brew teas and even then its just a better practice to remove them
No they cannot be interchanged and you dont want to use baking soda.What are the byproducts and other reactions of mixing ascorbic acid with chlorine or chloramine? General Hydro pH Down is using phospheric acid... how do those 2 acids react with one another?
Can phosphric acid be replaced with ascorbic acid - not sure if a lb. of crystal C is cheeper than a bottle of GH pH Down, but if so and ascorbic acid isn't going to cause adverse reactions with other elements, I'd see no reason not to switch...
And for raising pH, can simple baking soda be used as a substitute for GH pH up?
Awesome. I was kind of thinking ascorbic acid (aka Vitamin C aka citrus acid) would be more expensive than bulk food grade phosphoric acid (and it's a bit weaker acid).No they cannot be interchanged and you dont want to use baking soda.
Baking soda is sodium bicarbonate and while sodium is a micro nutrient in thw anounts used it can be toxic.
A cheap alternative to PH up is actually blwhat GH i think uses to make theirs…. Potassium bicarbonate or you can use potassium silicate.
Do not use citric acid as a PH down either. Just search for food grade phosphoric acid its cheap and the higher the concentration the better and less you will need ti adjust ph
No problem… yeah they use a combination of now I rememberAwesome. I was kind of thinking ascorbic acid (aka Vitamin C aka citrus acid) would be more expensive than bulk food grade phosphoric acid (and it's a bit weaker acid).

Anyways, thanks for the responses and insights into pH management.
Man it’s been a minute but between being, work, all shit that needs to be done around the house, and having our first kid, and then throwing in this hobby I’ve picked up it’s hard to find the time to reply.No problem… yeah they use a combination of now I remember
