[papasmoke]

I am in my 5th week of flower. I was wondering what steps to take from here on out. When do I start leaching? How much? Are there any other nutes I should be using? I am using Tiger Bloom now. What should I use for the final feeding? I was thinking Cha Ching,Final Phase or Bud Candy. What do you think?
Help me harvest this lady right, please!
