2 months ago, I bought D'Addario strings with specification:

1. 80/20 bronze
2. EJ10
3. Extra light gauge 0.010-0.047

And then my G-string broke and I bought a new set

1. Phosphor bronze
2. EJ16
3. Light gauge 0.012-0.053

I changed only the G-string with the new one. But I am finding it difficult to tune it to other strings both manually and with help of tuners.
Even when the tuner shows perfect G, I can feel it simply doesn't sound right. I can not explain but something is there.

Shall I change the whole set or there maybe other reasons?
