I use regular 7.0 tap-water on my entire garden, straight from the hose even 8/
Tomatoes, Watermelons, Basil, Parsley, Thyme, Strawberries, Chillies god the list goes on but you get the idea. Half of these plants are in pots, and even the tropical plants like Baby Woodrose - potted - recieve straight-from-the-hose water, and not a plant on my backyard is looking anything less than perfectly healthy.
The only thing that chews at their health are - no, were - catapillars, and now I simply nuke them with thr most poisonous shit I can find, even they aren't causing issues.
Plants just don't care about the growers techniques. All they care about is having enough water, aerated soil, nutes and sun, and they are happy as pigs in shit.
