Customblend thinset ?

[highcountry]

While installing floor tile over Ditra in a rather large project, I ran out of thinset (Custom PremiumPlus). Being in a small town the only unmodified thinset available was Custom's CustomBlend. Obviously, a step down, but at the time I wasn't concerned. I only use a bag or so before I realized what exactly I was using.
My quesion is whether this will turn out to be a big mistake? This is new house construction, so the floors are very structually sound. Is this thinset going to hold up?
Obviously, I am very worried, but its too late to turn back the clock.

Ive never used ditra myself but alot of folks have. Im sure someone will
be able to give an educated answer to this question.

CustomBlend. Obviously, a step down,...

if only that were true!! The good news is this isn't a shower that would get it wet. If it's only a couple of days old you can probably rip it out fairly easily, but longer than that and I suspect the pros will tell ya to leave it alone. keep yer fingers crossed.
