Northern lights autoflower

I just now added a top feed drip system with a 5 gallon reserve. i set my reserve at 500ppm and a ph of 5.8. and i have it set to water every 2 hours for 1 min. we will see how it works and update next week. i have only the 2 1000w led lights going for all 3 plants. i also installed an air conditioning unit so i can keep the room at a steady temp of 75 that way it will take less bottles of ice and effort getting the solution down to 65 degrees which i have been keeping it.
