Hey brother! Welcome to afn. Head on over to the new growers section and begin a thread, you'll find tons of help. We need some more information to be able to help you. What nutes are using? Medium your growing in?lightening etc.... Definitely is looking a little hungry to me, but don't want to tell you to go feed when in fact it could be ph lockout. Do you measure your ph? You know your run off ph ? Someone will be along to give you a hand. Welcome again to afn!
