This was 20+ years ago I was growing hydro and that’s all we used was one bottle for veg and another for bloom. I have not a clue as to what it was called but that was the only thing we even had access to where I lived at the time.

We also had NO idea what we were doing and flew by the seat of our pants, in lore way than one!!!

I enjoy good weed ........ where I live I am forced into growing inside.
I am pushed for space and need to make the most out my grow space . two 4x8 tents and a 4x5 walk in closet. about 86 square feet.
I enjoy growing weed, it is a hobby too.
My DIY hydroponic system and nutrients seem to have slight changes every grow . (Fine tunning )
I am learning more and more and by doing this I am able to buy the right nutrients by bulk or buy another brand.

Above all I want my grow to produce good or decent weed, I want to secede first .

Enjoy the weed you grow.

Couldn’t have said it better myself!

I really enjoy growing, even though I don’t smoke that much. I give LOTS of weed away LOL but I enjoy it.

I am most certainly sure that I will mess up during this process, then I will come here and ask questions and figure it out for how it works for me. That’s what’s great about this site is there are some many growers with a ton of experience and willingness to lend their advice

Well hopefully an inline filter will get me below 300.

 

[Ke0ncp]

Actually it settled a bit and 300 shouldn’t be a problem.

 

[Zeefarmer]

My RO water is under 50 PPMs when I get done adding nutrients its about 800 to 900 PPM's which is a little high .
I am using about 50% of what dosage is recommended on the bottle.
300 PPM's is not allot but it will effect the PH and the amount PH up and down you use.

Zeefarmer, Have you checked those numbers with a separate EC meter? I had a meter on the truncheon PPM scale that doubled its numbers. Would explain your readings. RO should be 25 displays 50. 1/2 strength should be 350 displays 700. That meter had me running circles till I figured it out. Plant was happily flowering at 3300 PPM AKA 2.35 EC.

KeOncp, .Your water report was on the hanna PPM scale. .62 on that scale is just over 300PPM. Carbon filter will pull the 60 PPM of chlorine right off the top. A basic, single, 5 micron filter should get you below 200PPM or .4 EC. Starting water of .4 + 2.4 of nutrient= 2.8. That leaves .2EC or 100 PPM of wiggle room. That is your target because the res should not go over 3EC because that is maximum saturation.

Visualize your water as a plate. 3EC is the max size of the plate. Starting water EC is what is already on the "clean" plate, taking up space, before adding the meal. Some of the micro minerals already on our new plate are like the vitamins and seasoning we need to add so a good base. Some of it could be like that sprig of parsley. Taking up space with no real nutritional value. Now we add our micros from the recipe, vitamins and seasonings. If our plate started with a bunch of salt and we add more salt it will mess up the ratio some. If we knew our plate had salt we just don't add as much. Then we add our macros. Meat, fruit, veg, and carbs. If your plate is full before you finish getting all of the macros they will just fall off the plate. You will see this as a white powder buildup in the res. If nutrients are falling off/out you won't have a balanced meal. First sign of not having a balanced diet is the PH will shift. A bigger serving of micros results in less room for macros. What minerals you are starting with, in the water, matters just as much, if not more, than how much you start with. Knowing what is already in the water allows you to adjust what you add.

500 scale is Hanna(USA), 640 scale is eutech(EU) and 700 scale is Truncheon(ASIA). There is also another scale from Asia that I don't remember the name of. Truncheon converted to eutech X 2. The reason PPMs were not allowed in school or any green houses, miscommunication.

Great info!! And looks like I should be good to go with my tap water through the filter

I need to start playing with my nute calculator to figure out how to raise PPM. I don’t think it has a PPM target in there with a starting PPM value, but I am not sure. More to come on that!

Thanks again for the info @Sativa1970

I'm not sure what nute calculator you're using, but mine (hydr0buddy) allows you to enter your water profile and it adds it to your finished targets
