How to make the link ECourse start with a lowercase 'e' and how to space the menu links

How can I make the menu link ECourse start with lowercase 'e' (i.e eCourse) alone and space the menu link. Actually, I asked about how to make the menu link align in-parallel with the logo, while my boss needs a quick fix and was hovering on me, I used this snippet;

/* tweaking the menu */

#main-menu > > li > a {
padding: 9px 10px;
text-transform: capitalize;
font-weight: 600;

Now, I want only the ECourse to first alphabet to be in lower case and space the links. Shot:
