The correct NPK for growing weed in veg is 10-10-10 and 10-30-20 for flower. I have grown some very fine smoke using that formula. There is not a lot of difference between 3-1-1 and 6-4-4. Both will work but some strains will lock out P and K if you use tooo much nitro for too long. I would start with what you have and change later on to a 10-10-10 formula. I use FF grow big 3-1-1 and mix it with BioBizzBloom 10-30-20 to make 4-4-3 which is very close to 10-10-10. They go by percentages so 10-10-10 is basically the same as 1-1-1. I never go full strenght with any nutes now that I use a ppm meter. All nutes are too strong to go full strenght. Good Luck with your grow show!
