First of two simultaneous responses --

NaOH should be approx. 110 g/l. It can make the whole difference!

Second of two simultaneous responses --

Your concentrations sound on the low end, but acceptable. Have you run some hull cell panels? This would not only quantify your concept of "low juice" and put some real numbers on it, but would also eliminate several possible trouble spots like defective rectifiers.
