when do i use pk boost??? some people say for 1 week and others say a few weeks?? dunno what to do for my grow???
It really depends on the nutrients that you are using for flowering. A lot flowering nutrients already have plenty of p and k, but late in flowering when you reduce your over all nutrient strength sometimes it's good to add some P/K to keep those levels up for a bit longer. Too much P (like anything else) will stress the plant though and actually stunt flowering.
Week 4-6 depending on how long your particular strain flowers for. PK boost is mainly used to increase budsite production and density. Less is more with things like this. Start slow and work your way up, you don't want to burn your ladies!! Also try looking up specific feeding calenders for your own nute system. Google is there to help!
