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 ⇦ huh? 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.
