how often to use ferts???

ive decided to grow super silver haze when in veg how often should i fert and also in flower how often to use ferts? also i have a 9 ft ceiling how high should i let her grow to have the most yield potential? i would like to pull somewhere between 1oz and 3oz off of her please help thanks


Also im wanting the bottom of the plant to have buds also how do i go about making that happen?

would it affect the plant in any way if i used foodcoloring (pink,purple) in the water (sum bill nye the science guy type stuff i know) but just wondering

remember that when she goes to flowering, it grow up at least 2 times bigger.
vegg too much and height problems will appear.
during veg, i used 2 times a month 20-10-10 and 1 time ricinus pie (only nitrogen and carbon)
