Congratulations on your first pods! Ripening times vary according to the variety, with milder varieties usually ripening faster than superhots. You're looking at about a month under ideal weather conditions. You can Google your specific variety to find out exactly how long it usually takes.
Your plant won't need more water than usual, just continue watching the leaves to know when to water. Be careful not to over water, as that can lead to cracks or bursts on the fruit.
While bone meal contains calcium, it's not in a form that's ready for plants to absorb. It needs to break down more in the soil first. Epsom salt doesn't contain calcium, but helps the plants to take up calcium more readily. Have a look at websites or stores that sell hydroponics supplies, they will likely have a water soluble calcium supplement you can order. Or just go to a store that sells plants and fertilizers and ask them for a water-soluble fertilizer that contains calcium.
It is not recommended to use household products to change pH. People do experiment with vinegars, baking soda and other items, but you will have the best results using products designed for the purpose. If you're growing hydroponically, it's easy to adjust the pH. However, if you're growing in a soil mix, it's best to prepare the mix and add amendments to reach the correct pH before planting. Unless your pH is wildly off and actively harming your plants, don't worry too much about changing the pH now.
It looks as though you're all set for success, once the fruit sets, you're pretty much in the clear. Now you just wait for it to ripen and then enjoy the burn.
