I have been editing this thing like ten times to make it easier to understand. Which now I am not sure I do anymore. LOL
ppm counts range from 900 to 1400??? whuts that all about?
Plants need different ratios of nutes during its growth cycle.
Also each meter is different in how it measures. so you will have numbers all over the place depending on the meter and if the owner has colibrated it correctly. (from what I read the Blue Labs Truncheon) is one of the best, no calibrating and crap.
OK I found this on another site:
"Allrighty then here it is the GH feeding program that has been
worked out to exact measurements..its perfect for all newbies wanting to use GH ferts ...... Al measurments are per 1 Us Gallon(3.785L) of water..

To use this fert you almost need a ppm meter. It is PH buffered so it is unlikely that PH is your problem, it can be...but more than likely your PPM is to high from your description.
it's the nitrogen which would lead me to believe you need more grow stuff in there
The yellow one is probably from lack of N, but if you PH is off then N will get locked out. So the nutrient is there, the plant can't absorb it. So increasing the fert will only make you PH problem worse, if it is a PH problem. Again need a PH test to know for sure.
Your best bet (without spending 100 bucks on a decent PPM meter) go get a single mix hydro fert like Dyna grow or fox farms. Flush out your system and replace with an easier to use fert for a first time. They have everyhting premixed. This GH is pretty complicated to get the mix right. I just read about 10 pages more than I wanted to find this for you. I use Dyna-grow and Dyna-bloom on my non-mj. (I am soil right at the moment on MJ until my next grow).
Invest in a PH tester. Before you buy anything else. That little bugger can tell you a lot about what is wrong.
Last thing. Is you medium staying moist enough at the roots with nute solution?
Sorry for the long post. At least find out your PH. I hope this helps a little.
