I forgot you had hard water dude. And you have lumpy normal purp (micro)?
NDW ever get with you about the hot water thing? On the bottle it has directions to add water to the mix when it becomes old.
The new 2 packs are better made now and are just as good as the tripacks.
I never used that formula tho.

quick question... can someone explain this a chart little better?

Calculated EC/TDS levels:

EC microsiemen:
0-4-8: 946 µS
0-5-10: 1184 µS
0-8-16: 1894 µS

TDS @ 0.5 conversion:
0-4-8 = 473 ppm
0-5-10 = 592 ppm
0-8-16 = 947 ppm

TDS @ 0.7 conversion:
0-4-8 = 663 ppm
0-5-10 = 829 ppm
0-8-16 = 1326 ppm

^^^I know what TDS and how much nutrients to use, but what is the conversions and also what is EC microsiemens?^^^ a
