feeding

hi, i have been advised to give my plants a weak feed, how do i do this, my feed was already made up by my friend in a 50ltr bin, do i have to make some fresh with less nutes in, i know this might be a stupid question but as a first time grower i want to try to get as many things right as possible even if these plants die,
they are supposed to have been flowering for 5 weeks now.

for the most part it looks like you have it almost there, just missing a few things and overdoing it on some others. Look at SubCool's soil receipe and us that as a base.

ps, where is the grow? is your friend going to go to jail with you if caught? are you legal with your MMJ card?

Dont tell anyone!!
