Planted feminized seeds and all the 8 plants turned out to be female. This is about 2weeks at flowering stage and most developed among them. Havent used any fertilizer rather than banana peels. Is topping sativa plants worth it ? only 3 out of 8 plants have started flowering stage and others havent started yet. they all started at same pace but some kept growing and only 3 started flowering . Any suggestion would be helpful
