I'm 42 day in flowering and buds are extremely small,dont know if it's my 600 watt hps bulb or wasn't enough micro nutrients, I'm thinking my bulb needs replaced ,what you guys think ?
Yeah, they do look small for 42 days! But it could be just a trait of the strain you are growing. What strain is it? And what medium and nutrients and supplements are you feeding them? As for your lighting, yeah, older lamps can greatly reduce overall plant development, but not to point where buds would develop slowly!
