I will be starting my first grow in a couple of months and I am trying to get as much info as possible so I am wondering a couple of things. I will be using soil with little to no added nutrients. What are the numbers for N-P-K that should be used? both for vegetative and flowering stage? When mixing the soil how would i do it Example- 1 gallon of soil, I need to add 20% nitrogen so i would add 20/100ths of a gallon and add it in? How do I flush the Plant when it is close to harvest?
get some soil or 3b mix add vermeculite and some shells or pebbles... no nitrogen till they get alil bit bigger
