Making multiple threads on the forum with the same questions just makes it more difficult for people to help you. Stay in one thread, it's easier for everyone.
I'd stick with Matt's advice to cut the stalks off for now - I agree with him. Cut them as low as you can without cutting into other flytrap leaves. The exact spot to cut really doesn't matter much; just cut it low.
The base of a flytrap flower stalk, especially the portion nearest the plant, often starts turning reddish in color while the stalk is growing - this is normal.
The reason Matt is telling you to cut the stalks is because flytraps use a lot of energy to produce stalks, and yours looks stressed and seems to be unable to produce a full flower stalk. This generally points to the plant living in improper conditions, be it improper water, soil, inadequate light, pests etc. (it's probably not pests).
Sorry I know it isn't what you want to hear, but we'd hate to see you lose the plant.
You said you're using rain water in another thread I think, which should be fine unless it's been sitting around in ceramic or metal containers, in which case it may very well have picked up some mineral deposits. The only way to tell for sure would be to test the water you're using, using a TDS meter like
this one. Usable water should come up with a TDS meter reading of less than 50ppm.
What soil are you using? You mentioned in another thread that you can't find proper soil, so is the flytrap in whatever soil is came with, or are you using something else?
How much direct sunlight (no obstructions between sun and plant) does it get per day?
Lastly, if you move the plant around (take it outside in the day and bring it in at night), that can stress out the plant as it needs to adapt to one environmental; not two. The temp, humidity, etc. are all different in the house vs. outside the house. Changing a flytrap's environment causes stress.
