Mexican Airlines Auto Fem

Mexican airlines definitely excelling over my other plants that i started atleast 3 weeks prior. So i changed my light schedule to 12/12 for about 5 days now and on the 3rd day pistil appeared so definetly showing gender. Sitting at 12in from top of soil. Havent made any changes to fedding schedule yet next feeding will be adding bio bloom bio bud, and i will no longer be using bio weed. After 12/12 lighting schedule change plant grew 4 inches in 5 days
