Would it be normal to have only clear instead of white ejaculate?

The consistency of male ejaculate varies -- not just for each male, but it can vary on different days. It can be thin to thick, clear to white. Sometimes, the consistency depends on your fluid intake, meaning, if you drink a lot of water, the ejaculate will be thinner. As a side note, the same is true for other body excretions: if you don't drink enough water, you can have drier stools and constipation, you can have thicker blood which the heart then has to work harder to move around the body, and you can have less saliva.
