water?

Plain ol tap water will be just fine...........distilled water can strip elements from your plant via a process known as "reverse osmosis", so I wouldn't use distilled water personally. Aged tap water is your best option if you have the time and inclination.

I would go to a charcoal filter for your watering needs.

Thats interesting has anyoñe looked into floridated water effects i know it occurs naturally but they put a chemical waste version of that element in city water

If you pay for water services, then see if they have test results available. My area list separate Chloride and Chloramine ppm's. Plants need chlorine too and tap has that along with other stuff like Ca, Mg, Mn, S, etc. If you are using a diverse micronutrient mix, then distilled water is fine.

you'd be better off with distilled or ro, but there's nothing wrong with tap, either. I used quite hard tap water for a few years and lately been using softened water due to ease / convenience and having no problems with that either. Th econcentrations of what is in it are fairly low as far as what would impact the plant... might need a little more magnesium or calcium but won't be a ton difference. I haven't had to change how i dose my plants since ceasing using plain tap. it's been enough days to see if any Mg issues cropped up (those Mg-specific symptoms lag 30 days behind or more and no Ca-def signs since then either).

I would see what your tds is for your tap water first but if you've given it to your plants and haven't noticed any adverse effects I'm sure you're fine and yes it would be better than distilled unless you added everything yourself. Hope this helps.

I saw your little plant and the color is perfect. If you've only given it water, it's likely that your EC is a bit high.

it depends a lot on the part of the world where you grow in Italy, we generally have good water and there's really little chlorine but many let it sit, but the problem is that decanting should be done with a stirrer and an open bucket to allow the chlorine to evaporate and the water to maintain oxygenation that said, you should be able to know how much EC the water has if you have a meter, it's simple; if you don't, you can check the water data for your area online if you use distilled water, you always need to add a base of cal mag and then supplement with the other fertilizers, and it's better to have the meter for that I chose to take the water and use it right away to have it more oxygenated
