yesterday my plant seemed to start dropping but i thought it was just me. today morning i look at it and it looks worse. here is a picture i took today? this is my first grow and its growing under 5 27 watt cfls. the water is ph'd and the temperature stays between 75 and 85. i water it every three days or so when the dirt is dry. the only thing that comes to my mind is probably because i havent started feeding it nutrients. it has been vegging for about 4 weeks already. any help?
