Purple Haze Photoperiod

I am finally seeing the flowering and the buds growing. I had 7 plants die from root rot. My fault, my inexperience caused it. The last three I worked my ass off to have them survive. Now I need a little tip on specific nutrient schedule, UV-sunlight, and watering. I'm in Sunny Miami, Florida. Watch-out!!! Hahahahaaa

I'm adding a little more information: I started using lights and then decided to simply grow outdoors in 5 gallon pots. What a difference and less tasking. The tent outside with the lights was very helpful in the beginning, once the plants got bigger, easier to just keep out and let mother-nature do her thing. Rain, sun, wind, humidity, it didn't matter; it's why they call it "WEED" The three plants were just about dead, from root rot, and some real TLC has allowed them to survive. Now blooming!!! Any advice on the nutrient, watering, and sunlight schedule to reach harvest? Thank you
