most first nation/indian reserves are selling clones in ontario or ask your local weed supply shops they usually have a few people they can hook you up with. I've also heard of people getting brave on facebook and doing clones.
clones are seasonal and you want them all gone by end of july for summer so get them early. i have mate at res and mid may is when he wants his clones to put out for sale. he'll do a few in late October but less buyers for winter grows so less to buy.

PM: **potassium bicarbonate** mixed into a gallon of water and 1½ cups of milk(low-fat, skimmed) or baking soda, dish soap, veg oil AND most important keep your zucchini plants far away from your weed.
note: buds are sponges and can suck up milk and cause other mold problems, so only veg spray.
Buds: alkaline reverse osmosis water spray, PM no like high ph water.
Best solution is prevention: bubble( aerated for 24 hrs ) water, some worm casting and unsulphered molasses and spray once a week or bi weekly in veg . i time my sprays to cloudy days best to soak plant down.
edited: i also add dutch nutrients enhance (3-1-1) to all my foliar sprays, seems to work well for me and they advertise 100% organic.
