Eggplant/berenjena

[alaskaa053]

I have some plants of eggplant this season, in two different gardens. In one of them the fruits are gorgeous and purple, but in the second one, though it is bigger, the fruit looks really pale. Is this due the sun, the soil or something like that or it simply needs to mature?

In Spanish, please.

Probably you are growing two different varieties.
