What's the difference between a plant becoming a Male & Female? Threatening the freedom/ confining the root system. With a confined Rooting area, as you have now, Nature knows, the Female knows She can't go to full term (making Buds & seeds) with such a restricted area to feed upon/in. She will Male-out. Males develop pollen a lot quicker than the time it takes a female to come to full term, so to save the specices, at least do SOMETHING helpful, a potential female will be a male. Plenty of (rooting) freedom, no stress, etc., your male/female ratio can be 80% female/20% male. Mother Nature knows that 1 Male can 'fuck LOT'S of Females, so the ratio, in a very good, idea enviroment will result in more Females. I hope it's not too late.
I lived a few miles from a Mushroom Farm. $20 bucks a pick-up truck load of Mushroom Compost. There is few things that you can plant straight into, without anything else. The list is, #1.) Rabbit Manure; #2.) Alpaca Manure; #3.) Mushroom Compost; #4.) Wormfarm Soil. That's the 4 that I know of. Lot's of people use it around the area, straight, if they want. A worm farm, using straight Rabbit Manure is the best shit in the world. Second is Rabbit Manure, which Rabbit Raisers will give you for free. I got 2 truck-loads at $10. per truck load. If you must pay good money for Mushroom Compost, add seaweed & molasses immediately to the soil/compost. Vortex by Lady Bug is good to add. Hope this helped.
