when should marijuana be feed

hey just started growin marijuana and they have just sprouted and just wanna know when should i give them fertilizer and plant food im growin afghan as well just in case also if u kniw were to get some good and cheap top 44 seeds plz

i only feed when it looks like it needs it like yellowisg leaves in veg ect.

After 5 sets of leaves (Not including the first two little circular leaves) you can add nutes/ferts. Use a little and work your way up (but don't add too many nutes, you can stress your plant out).

Also allow the soil to dry out inbetween waterings, the roots need air just as much as oxygen and constantly having the soil damp will suffocate them.

you can start feeding after the cortyldons or first set of rounded leaves die off but i only feed when they look like they need it
