Thank you, this is helpful.I wish there was a less expensive way to ship to you nice people in Canada. On consult with Doc....feed weak nitrates (calcium nitrate) in veg and use some ammonia based nitrogen when they start to flower. A good one would be ammonium sulfate. Fishy ferts would also work, but not quite as well.
Are there organic alternatives to calcium nitrate and ammonium sulfate?
