Redish brownish leaves

[nepenthes_freak]

Hi all
I just recently got some plants and a lot of them form a little of of a reddish sometimes brownish spots all over a few or one leaf or leaves. Is this normal and should I worry? They are like peanut1gangs amp which has the big green pitcher on it, the photo is on the thread neps and others. Thanks!

I wouldn't worry too much but do keep an eye out for humidity and air circulation problems. I've noticed that with my plants, high light levels cause the reddening in blotches. Older leaves that are dying can have the same look as well. Just make sure it's not fungus.
