i have 14 white rhino plants, theyre around a foot tall and look healthy, i want to (obviously) get the maximum yield that i can. i have two 600watt lights hanging 2 feet from the tops of them, i feed then terra vega every day around half a litre each, am i over feeding them? are the lights too far from them? i want to grow them to around two foot before starting flowering, when i begin to flower i was going to put another 600watt light on them, would this be worth doing or are the two i have going to be enough or will the extra light give me more yield? its my first grow and some help would be very much appreciated, the room i have them in has good in and out ventilation and the room temp is between 20 30. i'm most concerned that i have the lights too far away from them, is this the case?
