I just use epsom salts
Cheaper

Epsom salt has no Ca, just Mg and S.

It did help thanks! I run a lot of pure distilled through them to flush n b ready for flower and I think there finally responding to it anyways ! Looks like it’s coming around donno fully yet tho praying

Don’t flush them with pure distilled water. You don’t need to flush before harvest anyway. If you want to cut the nutrients back before harvest l, then that’s fine, but the water still should be within the correct pH range and it should still have some minerals in it. I still don’t understand why you think you need to use distilled water when you are also using tap. Just use tap.

Because up salt build up, it’s not RO it’s filtered

N god knows what’s in my tap water so I like to go st least half and half distilled to make sure I’m half safe at least

Soft water I think the ppm mite b 90 or it may be 0 now I’m not sure yet but I know it ain’t high

it sounds to me like you need to stop guessing and just figure these things out. If you keep guessing what your soil pH is, or whether your tap water is suitable or not, then every adjustment you make is pointless and being done blindly, and nobody will be able to help you figure out your issues. Most tap water that is safe to drink is perfectly fine for plants. I started out using RO for all my plants and, when I got tired of all the waste water going down the drain, I went to tap and have had zero issues.

The salt builtup is mostly due to mineralic fertilizer. If you're doing this you should have around 30% runoff to waste and that'll prevent the salting out, because the old solution is forced out of the pots leaving only new mineral solution for the plants.

But your plants look well, maybe you can move some of the pots around to get a little bit a better light distribution as some plants are quite small, other more large, and move some to the sides, the big ones to the corners, and give them sufficient light for now.

I just did I just added another 600w hps now it got 1 mh 1 hps in there for two week then both hps going in the 5x5 lol

Don't need it with well water

Hi just wondering though how tap water with chlorine and god knows what else with a pH of about 10 would affect something growing in living soil. I would live to just give tap water! But something tells me it would ne detrimental to the crop.

how much electrolytes are there in?

25 micron carbon filter, dirt cheap. This will remove most the crappy stuff at a high flow rate.

Im not claiming that everyone has suitable tap water. I’m claiming that a lot of people who just assume they can’t use their tap water usually can. The only way to know how bad your water is would be to read the annual water test results (if you are on public water) or send a sample in to be tested.

BTW, if your tap water is coming out at a pH of 10, then you might want to calibrate your pH meter or invest in sometest strips, because I’ve never heard of anyone’s tap water being that high. Milk of magnesia, a common antacid, has a pH of 10.

how much chlorine can Cannabis tolerate anyway? will 25mg per liter be too much?

I don't remember, but higher than I thought. I just don't want it killing all my microbes.

Mine comes out at 45-90 ppm (in at 125-200) with no chlorine after a simple carbon filter.

Chlorine is easy to remove. A charcoal filter will remove it or, you can just fill a bucket up and leave it overnight, and it will gas out of the water naturally. Chloramine can be more of an issue in higher concentrations, because it can’t be removed in those ways. The only way I’m aware of to remove chloramine is with water conditioner, which comes in a liquid form, or with an RO filter, but not all water treatment facilities use it.

I understand that both genetics & the environment both have a huge influence on actual numbers, but what would be good for starters would be a table with recommended estimated or grossly averaged numbers of N P K Ca Mg S Fe Mn Cu Zn Mo B Cl + maybe even potential beneficials like Si Na Al Si Au, but from what I understand is that Cl is actually even essentiell for hemp to grow so it's maybe a good idea to think on precise numbers on this one... and I think one shouldn't overdue it with Cl for it has a huge osmotic potential and can therefore decrease access to what a plant would otherwise get from minerals.

I'd like to have a testing kit at home to check in on the happiness of the soil life - it's too tiny to see anything.

I shouldn't have said no chlorine, thats technically incorrect. I can still smell some traces but it's low enough to not be a concern at all.
Chlorine is a trace element that excels in bonding to other chemicals, it was surprising to see how often it appears in nature.

Mostly the filter just takes out the water department's bad days, like hydrant flushing in spring, or dousing the water system pipes with extra chlorine during the summer. I don't have enough calcium in my water, so I always have to add it to the soil or water.

Indeed it's only inferior to Fluor, then Brom, Jodid... Oxygen. Some of these halogenids are so heavy, they are mostly found in deep water. Chlorine is quite light in comparison and is basically everywhere, perhaps in every medium? Even rockwool, how abour aeroponic? RO water + bottled salt nutes - where would the Cl stem for? What would be the absolute essential minimum?
