Wrong FoxFarms Grow Big nutrients- suggestions on how to catch up PLEASE!!

What up all!!! So here is the dilemma, Im on my first grow, 4 lovely ladies, G13xHaze or Mango or White widow. These are the types of mothers that my seeds came from. N-E- Way, I have a nice and small Bubbleponics/ CFL set up going and things are moving but I knew for some reason they were going pretty dam slow. What I have just reallized is that the guy at the Hydro store started me with Foxfarm BigBloom, and Grow Big which I thought was cool but it seems like its the wrong Grow Big. The numbers are 3-2-6 and I found a Grow Big that is 6-4-4. I feel that this has caused quite the growth stunt and size problem. Does this sound correct? This is my first grow but I am an avid reader and applier, so please any suggestions on playing catch up are greatly appreciated. Should I go get the 6-4-4 or just double up on the 3-2-6? Is there a savior nutrient that I can get? Thanks again. Stay Irie.

Don't change anything. The 3-2-6 Grow Big is specifically formulated for hydro, where the 6-4-4 is for soil. Do they seem to be lacking N? Yellowing fan leaves and all?

yes lack of n and seems like the stems are a bit purple. Ive been trying to stay on top of the ph, but I dont know
