Ok so if im using a dwc kit and it says use a teaspoon of nutes for every gallon and its a 4 gallon resevoir how many nutes should i use if my plant is just about to start its 4th week...i already used the full nutes and it gave it nute burn so ive been flushing it with just ph correct water so should i add just half nutes or even just a quarter of the nutes as last time?
