I'd hit their website. I just checked, and it & looks like it should help. You may be under feeding.. which is why growth may be a little slowed down... but a lot of other variables come into play as well. Environment, light intensity at the canopy, leaf temps, root health and more. Growing isn't so easy at first.. but you're documenting & that's a good thing to fall back on "Notes" You can find the most experienced answers to a lot of questions within the threads here on RIU. Type out the issues in the search tab, and you will see the threads related to that. Lots of guys may come give you shit if they have to tell you something they helped out with in a thread here back in 2011 lol I've been growing a little over a year, and I think I've come pretty far from where I started.. check out my progress up until before I started my current run. I have threads on my 3rd & current run linked below the pics if you want to check em out.
Here's my 1st plant... as you can see.. no leaves.. I burned all the fan leaves & it was good for nothing but hash... even that tasted like boof lol
