Don't believe the hype about nitrogen setting back pods. It's not that at all, and if it were, it would have to be more nitrogen than what Miracle Gro gives you. If the first leaves are huge, this is a function of your environment. Temp, humidity, oxygen levels, etc. If this were my plant, I'd remove the gigantic lower leaves. Where in Canada are you, and what have your temps been during the day and at night? (only answer that if you're growing outdoors)

Of course I don't have to worry about that, because it's so fecking hot and humid where I'm at, that leaves can't and don't get that large. But big leaves aren't a sign of your growing prowess. It actually sounds to me like maybe it's too cool for pods to set. But then, you haven't said what kind of plants you're growing. Or much of any kind of info, really. LOL
