Looking awesome, mighty frosty for 3 weeks!!! I'm on my first grow also, my setup is kinda like yours I'm 3 weeks into flowering, I have three plants in a 5x5x7 grow tent, 7 gallon pots, and a 600w hps. What is your temperature and humidity inside your grow tent?
How far away do you keep your 1000w off the canopy?
Every strain is different but if your light is air cooled you might wanna be closer that a foot but if your light runs really hot best keep it a little bit further i can post my feeding regime im giving them its not perfect but i has my girls growing nice
Ok, I keep my 600w at 20 inches (not aircooled) above the canopy about the same distance you keep your 1000w. I would definitely appreciate you sharing your feeding regimen.
You're going to feed with every watering? You're not worried about over fertilizing?
PH? Having the proper pH only ensures that your nutrients will be available for the roots to uptake, it has nothing to do with your waters Ec/ppm which is the cause of over or under fertilization.
