I just started growing... and my plants have just broken the soil... while i was high... my friends and i came up with an idea... when we toke up.. we always take out the stems to improve taste ... will grinding up the stems and tossing them into the soil improve my yeild at all??? or is it just a waste of time??? Three plants have borken the soil.. they are about an inch high... one of the leaves on one of the plants is dried up at the end.. and yellowing... while the other is dark green and seemingly quite healthy ... the other two plants also look healthy.. what can this drying leaf by from??? Is it too soon to use fertz??? and at what tempeture should my grow room be at?
