yes the strength of the base was way low at first. I had cut back on base nute to add (N) supplement and get a proper ppm reading the guys at the store said this is where I made the mistake possibly because I wasnt using the meter properly "so to speak" I was reading right but using it as a sole instrument to determine my nute stregnth. the guys at the store told me to always follow the directions for the base nutes first, then add supplements if needed or wanted. whats your opinion? how do I determine exactly how to use this ppm meter top my advantage? plus my RO water isnt really RO water in combination with the other things I am not sure how to fix my problem and exactly whats wrong.
Just the opposite, additives first, then base nutes typically to get to desired ppm's. But, go easy on any additives for now - I have to run, but I'll check back when I can...
If/when you can... Check your ppm's after all is mixed up, then let me know what they read, and what brand / model you are using (it matters, believe it or not, unless it's measured as EC, which is universal... ).
