My NL#5's are 25 days into flower and are dropping all thier fan leaves. Is this normal??? These babies are 4 feet tall and bud ridden. Have them under a 400W HPS in a well ventilated 4'X5' closet.
sounds a bit soon, but its normal for plant's to drop there leaves , In the later stages of flowering....
Sounds like you need to feed that girl. She is taking nutes from the leaves to build bud. What is your fert and regimine?
