If your exsisting support will allow additional support on top I would say go ahead and tie or wire some more supports on top. You can also let them grow over the top and back down the support, in fact I would probably reccomend that over adding support. And no, they wont stop growing just because they are putting fruit on. They will get taller. Unless they are determinate varieties, then yes they will stop growing tall. Damon

The growing medium it is currently is in horrible. Get it into a faster draining mix like cactus mix amended with perlite (cheapest and easiest for most to do). Mix at at least 50/50 or go heavier on the perlite. You could even mix in some gravel to make the mix grittier. I agree with the others. Your watering regime is ineffectual. Water until you see it coming out the drain holes in the pot and then leave the plant alone. In winter, watering once a month is enough and may even be too much. Skip the moisture meter....a waste of money and you can do the same thing with a pencil/skewer/your finger....like poking a pan of brownies with a toothpick. If there is soil medium stuck to it, you don't need to water. Light is not really an issue here. These plants can live in shade for months and not be bothered. What I think is happening is that the mix in the pot has dried to an almost concrete consistency around the roots of the plant. Your watering isn't doing anything because all it is getting wet is the top of the mix. I suspect that even if you watered like normal, the water would not penetrate the "concrete". So, essentially, the roots of the plant aren't getting enough moisture, if any at all, and the plant is using up it's stored reserves and slowly dieing. Any water you give it is running along the outside of the mix and finding the path of least resistance to the drain holes.

Here is a link to many photos of the so-called "jewel" beetle family, the iridescents. You should be able to ID from the pics. https://www.google.com/search?q=iridescent+beetles&sa=X&espv=2&biw=1637&bih=925&tbm=isch&tbo=u&source=univ&ved=0CB0QsARqFQoTCIW58ZfA2MYCFQmAkgodX20GfQ But if you found only one then it is highly unlikely you have or will have any infestation. And what did the damage may even have already moved on. But it would be difficult for one beetle to do much damage unless we are talking about only a handful of plants? If you feel you have to treat the plants then DE (diatemaceous earth) is relatively safe to use. Dave

apachekumaran, to answer your new question, yes, your plant needs a normal pot with a drainage hole and saucer once it's stable (e.g. the soil has been dry and the rot stops spreading). Replanting it might be too stressful, but it's probably a toss-up between leaving it in place while waiting for the soil to dry out vs. disturbing it while getting it into a better pot and dry soil right away. I'm sure someone with more experience than I have will pipe in about which is better, and what kind of faster-draining soil this plant will be happy in. I don't know how your pot works, but if there's any excess water in a reservoir it needs to be drained right away, and in the future make sure that your plant's soil doesn't come in contact with water that has drained out (that is, no standing water in a saucer) As an aside, don't rely on what a potting soil's bag says; many soils that call themselves fast-draining actually stay soggy if watered on a schedule, instead of when the plant actually needs water.
