Ill be keeping my eyes glued to that Jacks/Chemgro thread. Eventually, the ultimate line up of nutes will be revealed. Lol

I may do a jacks/Masterblend comparative run in the next few grows once i get Jacks a little more dialed in. Ive got veg down, transitioning to flower and timing the final flush/switch are where my issues are right now. I see your work and Masterblend is absolutely a worthy nameā¦ either that or you are just THAT good!! Lolz

Be interesting to see how they compare, they are quite similar.
Weāll call it a culmination of both+good lights,coco,and a lot of reading!

I use jacksā¦not the 3 2 1 but the tap water planā¦since I use tap water and my water is on the hard side I donāt use any cal/magā¦they say to use bloom booster during the 1st couple weeks of bloom although I have used bloom booster through the whole flower cycle with good resultsā¦keep your ppm up around 1000 and you will be good!

@kosmc any idea what your ppms are in your tap water? My hard tap water is right around 400 ppm, with the softener its like 600ppm. Im currently using about 15% tap water and it keeps my ph right about 6 after mixing in the Jacks.
Yeah, mine is around 260ā¦artisian well waterā¦so when I check ppm Iām around 1200ā¦actually was chatting with a jacks guy and said for well water the
15-5-20 program works good so im giving that a tryā¦heres the schedual.

So simple
So the water you give your plants is at 1200 ppms? Or do you adjust it down from there?
right around 1200, with my water that makes it around the 1000ppm of nutes.

The question here is, when going to 600ppm with the softerā¦what exactly is the ppm or TDSā¦ or better stated, what is the make up of those solids that are dissolved.
There is a water lab that for $25, you fill a clean water bottle up with the water from your tap and they will analyze it and tell you the make up of it in the form of a water report. This can in turn change your mix based off your tap water make up. Possible reduction of the epsom salt quantity etcā¦
I used to do this quarterly when I was brewing beer because I often needed to change my salts I used based off the beer style I was making, because it GREATLY effected the flavors during the processā¦itās how I was able to quality control my product to ensure every beer you drank was the same as the last from keg to keg.
Thatās if you REALLY want to nerd out on it lol

Cut that factor out or greatly reduce the question at hand with filtration ā¦ is this the best? I dunno New York pizza taste better then most pizzas they say itās the waterā¦is there science behind it probably but I dunnoā¦ I think itās a factor everyone has to adjust to because if you have 150 to 350ppm out the tap and you can drop 80 to 90% out with RO and get 15 to 30ppm @ 150 originally and harder water goes to 35 to 50 ppm ā¦a very small amount but there is still something left ā¦what is it does RO remove more calcium ā¦ Magnesium chlorine ammonia chloromins iron zinc fluoride does your water even contain that you would need that test to see the minuscule amounts but at that little ā¦of any element isnāt alot and its probably a combinationā¦does anyone know if RO targets certain elements more?
A good RO system uses water pressure to push the water through a āmembraneā. That membrane is designed to strip ALL elements from the water. Whether or not it is able to strip it comes down to the quality of that part of the system (brand, design, age etc all makes up the quality)
You can have a brand new system work perfect for the first 100 gallons, then slowly diminish over the second 100 gallons so forth and so on, which is why they are sold the way they are and advertised as a quantity of gallons.

Is there systems that claim 0ppm? For any amounts of gallons?

My RO buddy from Amazon cleans up my hard/soft tap water to less than 12 ppms, used to give me 0ppms for the first hundred or so gallons. Ill change the membrane after this grow to knock it back down to 0
My water is anywhere from 500-750 ppms from tap
Wooowiiiee thatās some hard water
