Sexing Regular Plants Early

Regular CBD seeds mean roughly half the plants will be male, and waiting until they release pollen is far too late. Preflowers appear at the nodes around week four of veg, with males showing small round sacs and females a pair of white hairs. The photo guide on https://calmcbdseeds.com shows both at the earliest identifiable stage, which is clearer than most forum pictures taken much later. Checking every plant with a loupe every couple of days from week three saves the whole crop from being seeded.
