what people are talking about, is a PK 13/14 booster....
see in mother nature, in the begging of the summer there is lots of nightrogen in the soil.. as the summer goes on, it uses up the nightrogen in the soil, and when the nightrogen is all gone, the plant know... its the end of the year.. its time to die.. so it starts eating the nightrogen from its leaves... putting everyting it can o the buds... thats why alot of times when you see pics of plants just harvested the leaves look yellow.. cuz the person used some kind of booster to get the plant to eat its self, or just ran the plant with wattter so it would eat the excess nutriants out of its self...
well to makea long story sort, in your third week you do not want to jack up the P or the K you will give you plant a N deffichancy...
if you have a strain that takes 8 weeks to flower in your 6th or 7th week you can start using a PK booster... the 0-52-34 is the PK booster...
now the other stuff your talkin about the 5-10-5 thats what you want to keep using.... then around 2 -3 weeks from the end.. switch to the 0-52-34, then for the last week, just give them watter, that will flush out alot of the excess nutriants....
keep us posted
p.s. i wouldn't piss in anything, piss will lower your ph i'm not saying it won't work, just watch how much piss you use, if you so choose too haha
ohh, one other thing.... you can always order nutriant online... if your ever gona order stuff, i would suggest flora nova by general hydroponics for about 40bux you can get enough for a cycle or 2, if yur just doing a closit grow... its alll organic and works with bolth hydroponics or sole mediums
