what is this?

i seen it on plant problems before but forgot what is this.

this is my girl after haveing a duded last plant but the duded never got this -_-

just incase u need info

shes maybe a mounth old under t5s dirt nutes which is bat guno and wormcasting and water is all i give her water every other day bag is 6 gallons

how much nutes you give her?

if ya read i said i only give it what the soil has to offer since im still a newb to adding my own nutes i dont wanna over kill so i just tend to let it feed only on the soil and water

besides only nutes i have besides the soil is budcandy all this stuff i bought as a newb didnt know what i needed

if its been a month since plant, the soil is probably out of nutes.. need to give it some more food
