I think that was the answer to my question, but I am going to re-ask in a different way, just to make sure:

In week 10 the given nute schedule states 1100-1200ppm
In week 11 the given nute schedule states 1200-1300ppm

For this scenario I will assume that LK will be held constant at 5ml, and as we discussed, CM will max out at 5ml, thus will also be constant at 5ml per gallon.

To adjust the ppm upwards of roughly 100 ppm, I would simply add 100 ppm of PBPB, right?

I think I am going to break down and get a digital readout meter, at this point I've invested enough that it would be stupid for me not to have one, just incase I really do suck at reading the color charts.

Is the simple tester here HTG Supply - Checker pH Tester just as worth getting as the basic ppm meter was?

if not, any advise on a brand or type to get?


I really do appreciate all your help. I'm sure that as long as I can follow your advise I will get much better. I just wish summer would end so that heat wasen't such a pain in the ass, lol!

So, if you had to describe what a "routine" (if there is such a thing) watering went like, how would you describe it? If I were watching you do your basic feeding, what would you do step by step?

Also, any thoughts on LED lights? These summer temps are making me think that maybe I should start thinking about upgrading to those by next summer. Sure would help the electricity bills too.
