Is it normal that some of my e-liquid is turning thick, clumpy, and crystallized?

[Ctina914]

Hey everyone I bought 5 e-liquid bottles all of them have between 3mg - 6mg of nicotine. They were all liquids when I first bought them, but now 3 out of the 5 I have purchased have turned thick, clumpy, and have formed little crystals in the bottles. I have noticed lately the more I smoke I'm also now getting short of breath. Could theses liquids gone bad? Would it probably be best if I disregarded them and get new ones? Or could they still be good? Thanks in advance for any advice!

Here is a close up picture of the clumpy, thick, mushy, crystallized e-liquid I was talking about hopefully this picture helps... thanks again

Do they have menthol in them? Sometimes it crystallizes if it's cold.

I don't use menthol so I cant speak for that. But I have several liquids that are multiple years old & none of them have done that. I store my liquid in a cabinet with doors that keep out the light & the room stays cool year round.
I really don't think I would be trying to vape that.........seems like eating lunch meat that has gotten slimey.

Yuck! Send photos and a letter to the maker and dump that stuff. That's just not right.

Looks like direct sunlight for too long.

I can honestly say, that in my many years of vaping, I have never seen juice crystalize. I would dump it.
Out of curiosity, what are those 2 juices to the right?
