I've stopped giving NP and am only giving K for the last week. It's the first time doing this. All other grows I have kept giving NP till flush.
I have some discoloring of the leafs and pH is dropping tremendously. This should be all because of the P deficiency.
I'm ready to hear some tips. How do you people do it at this stage? 2-3 more weeks to go at this point. Should I add a little NP?
