the nutes of using consist of a a/b mixture, as far as i know the a part is a nitrate molecule, the ratio's that i used to use were 1:1 (before budding cycle), now im following an instruction guide given to me with the nutes from teh shop, and im using 7ml of a and 9ml of b to every litre of water, with 3 ml of the flowering agent. the indica plant also isnt budding...non of them are, but the sativa plants are growing through the ceeling. thanks for the responses.
