Blocked by Correction Ratio

Today is my 305th journal writing(time, or day) writing in my journal every day, so I was worried ifthat I couldn't write my today's journal.

1. In the first part, you can say "writing journals every day", "journaling every day"...There are many ways to say this part :) "journal writing" is also okay (if you mean it like journal-writing), but in that case you can just say "journaling".

2. "write my today's journal" (X) sounds a bit unusual. You can say: "write today's journal", "write my journal for the day", or "write my journal today" ("today" in the last one is an adverb, not an adjective)

In the notification message, it said I wasn't at the minimum correction ratio (1.0) to write a new journal.

When I saw the notification for the first time, I was shocked because I shwould have to help others' sentences through more than 1300 comments.

I think you mean that to reach that ratio, you must make 1300 comments, right? I changed "should" to "would have to" because it makes that more clear in my opinion.

For increasing the ratio, I tried to write comments on old sentences in Korean which were written more than 1 years ago.

Fortunately, there were 25 sentences which werehad no correction comment.

With more than 370 corrections, I finished writing all of them, thenso it is possible for me to write a new journal now.

I added "for me" because I think it sounds better, but it is okay to omit it.

Just reworded a bit to sound more natural and less clunky.

You mentioned in the previous sentence that you just saw the notification, so you don't have to state it again in this sentence.

ForTo increasinge the ratio, I tried to write comments on older sentences in Korean which were written more than 1 years ago.

"In order to increase the ratio" can also work here.
