If I did all my data entry correctly (most of those I didn't have in the database), week 10 comes out to:
264-212-226 with Ca: 0, Mg: 13, and S: 13
which is insane.
Here's how I got there:
And here are the results:
I won't swear to these numbers because I don't have time at the moment to double check all the data entry, but four of those bottles have nitrogen, three have phosphorus and potassium, and one has so much phosphorus it's ridiculous.
And the Ca, Mg, and S numbers are also odd.
I'll double check these later today and report back with any anomalies.
