This is my current setup , 1000 DE HPS (Dimmed to 750w) and six pots with living soil
Temps go around 20°c to 25°c and RH 30-50
Question here is , im having trouble because my plants are stretching.
I'm just looking for tips to maximize yield
It depends on the nutrients used on the run
most organic amendments dont requiere flushing, if ur using heavy salts definitely flush.
for flushing u want to decrease ur nutrient input from day 14 to 7, and cut off all nutrients last 7 days of flower
