I wrote this sentence
As they progressed, their problems were related more to finding the sound-to-letter correspondence. Now they tried (or were trying) a specific set of letters for each phoneme before grasping the spelling pattern.
Is my usage of "Now" for a sentence in past correct?
Could it be a special sentence (imaginary) with specific structure (for example needing would try or "were trying")?

Now is an adverb that can mean "happening at or referring the present time or moment."
Now also has another meaning - here's Google's take on it:
This might be how now was intended to be used above. In this case, it will typically be used in the first word of the sentence and be offset with a comma. Since now would be being used as a "flag of importance" the tense of the verb it modifies wouldn't matter.
