I've read so many articles about adding specific amounts of extra nutrients during this phase and adding other nutrients in this phase blah blah blah. Is it possible just to grow without having to add all of those? Just naturally? I'm growing indoors in pots and I can't really arouse to much suspicion and I don't really have much extra money to spend. I've already got good soil that drains well but retains good moisture and a good lighting setup, do I really need extra nutrients as well? I mean it's called weed for a reason, I imagine it wouldn't need to be treated like a king to grow.
