your tap is accumulating limestone in the medium and forcing the pH up,
calcium is being locked out as a result.

IMO the best options would be adding distilled or rainwater to adjust EC

in my experience a tap water ppm of 120-130 is the absolute highest i could
go without calcium problems.

oh, i forgot pictures, everyone loves pictures!

here's the full story on the jack's tomato feED label

That really makes sense. TY very much.

I've been using MaxiBloom as a 1 part fert but I've read through this thread and am interested in using jack's or hydro-gardens dry fert's. Maxibloom for me is very difficult to dissolve with multiple 20/gal reservoirs. How easily do hydro-gardens and jack's dissolve? Hydro-gardens 5-11-26 is better than Jack's because it contains more Micro's? Do you still use this feed ratio?
The 5-11-26 can take a while to dissolve, which is why its better to run concentrated stock solutions made with hot water. The endothermic reaction speeds things along, and the stock can be left to dissolve over days and be used as needed, instead of dumping raw salts straight into a res. It also helps to avoid undesirable reactions/precipitations since you are diluting elements in increasingly larger solutions. Calnit, for example, doesn't play nice with Mg, but a precip can be avoided if you simply dilute in stock then dilute again in the res.

No, I've since switched my ratios up a bit. I don't want to post them until I have a handle on how they've affected things. No secrets, I just don't want to advocate a mix until know the results of it.

All of this is excellent advice. :hump:

So dumping calcium nitrate to the reservoir in the form of a raw salt can cause precipitation? Mixing enough for 20 gallons at a time in a 1 quart mason jar would be diluted enough?
Use two buckets; one for calcium nitrate and the other for everything else. Add your desired amount of salts to each, mix to fully dissolve, then add them to your reservoir and dilute to your desired EC. Finally, pH the mixture last because dilution affects it.

Or just bottle up concentrated stocks and use at the given application rate. Couldn't be easier.

Personally I drop my potassium silicate solution first, fix the pH down from 9 with phosphoric acid, then run calcium nitrate solution before adding Mg then 5-11-26 then supplements (humic, fulvic, bacteria etc) before final pH check. Get this dialed in and pH shouldn't need any further fixing but still I always check.

Hot water and a magic bullet gets those salts nice and dissolved :clap: I use bioag humix that stuff is the worst to mix but the blending significantly helps out.

:clap: on the blender!

Hot water and a good stir whilst decanting into the final container does the trick well enough (I like to use my old GH gallon jugs as if to get my $'s worth out of those pricey bottled nutes).

Mixing potassium silicate leaves a soft, squidgy residue at the bottom that does eventually dissolve. The dust also stings the nostrils.

Mixing my stock of fulvic acid stinks like blood and metallic toast.

Mixing my kelp stock is an inky black mess, everywhere.

Mixing mag sulfate makes me want to take a nice long bath.

Loadsa fun.

couple of years ago in veg i used to spray blk water, it never stunk though. i also used kelp, the dte meal though, not the powder, so that might be the reason behind mine not being as black as yours.

Ahh, I see, so do you mean that your softener doesn't use salt, or that you just aren't adding any? Cuz if you're not adding the salt then I think that it isn't actually working, and if it's just wasting water flushing itself, then by all means you should just bypass it (if set up correctly there should be a couple of valves that will allow that).
I am not adding salt and i do not think this unit uses salt but not sure. I may bypass once I know more.

So if your tap water is at 290 ppm, that's pretty hard and could use some filtering. If you manage to bypass the softener, you can pick up a three part filter at say Home Despot or Lows for pretty cheap and try to get that down into the mid to low double digits. And unless there's a specific mineral in over-abundance in your area, I wouldn't worry about what's in there, it shouldn't make a big difference imo. ALthough it is good that you're paying attention to detail, sometimes it's best to just focus on the fundamentals and get to growing, cuz you'll learn a lot more as you go and steadily dial in whatever system/style you prefer. Iow, don't sweat the small stuff, you can't expect perfection overnight, or as they say, Rome wasn't built in a day ;?)
HD does not seem to stock any 3 part filter housings so will use distilled water for now.

i use jack's tomato feED for my ladies. i'm doing a coco soil with added
kelp/alfalfa/bone meal and mineral supplementation. i dilute my tap water
down to ~100ppm, then add 3 grams per gallon tomato feED and 1/4 tsp
per gallon epsom salt. crushing it with COBs, significantly over a gram per
watt since i made the switch from botanicare to jack's.
So I used this method and lowed PPM to 100. Now wondering how much citrus feed to add.
I used added 200-300ppm to make 3/400 pmm water then PHed then added.
Not sure if thats light but at least I am not giving them water that is way off PH and way to hard as i have in the past.

i would start with 3 grams per gallon, it seems to work across two well tested
jack's varieties and IME pH comes out perfectly using diluted tap water.

don't forget rain water! you can always collect a bit, boil it, and store in 5g buckets

does anyone use bennies with jacks? in either dtw coco or dwc. i have been running sterile with pool shock and although my roots look great i feel they could be better. i just ordered some og biowar and was wundering if anyone had any insight

all i ordered was the roots pack im seeing some people mix the roots and the foliar pack. i know next to nothing about running bennies

Yes, I've run exactly that and my advice is that you just wasted your money.
