Oncidium twinkle leaves browning at the tips

I don't think that the tap water is particularly problematical for most orchids. You might want to adjust the pH when you fertilize to improve absorption of nutrients, but for general watering, it should be fine. When I use tap water for fertilizing, I just use about a tablespoon of vinegar per gallon to get the pH below 6.

Thanks Roberta. I will follow your advice to adjust the pH of tap water using vinegar. Your orchids look so beautiful😍
