I am growing some sour diesel, and im wondering how much i might yeild. The picture is of the plant im asking about. It is 15 days into the 12/12 cycle. It is under a 400 watt HPS light and im using the 4 guanos for nutes. and have been following a chart for using the guanos. So if you have an idea as to what i can expect please let me know. This is my first grow and it has went pretty good so far.
