I started growing with an all LED setup and so far really like the lights. One problem that I've seen is that my temperatures are hard to keep high enough since the lights don't really put off a lot of heat. So I'm working on that, but had some nute burn that seems like it might be an LED specific problem.
As I said, temps in the tent are a bit low (low 70's high 60's) because I am growing in tents in my garage. I cycle my exhaust fan 30 off 15 on so that the tents have the ability to build up some heat, but I don't want the humidity getting too high. I am watering once a week, couple times stretching on to 8 or 9 days before watering. They just don't dry out as often. So every time I water it is time for weekly nutrients. I'm thinking that the reduced amount of water that the plants are using means that there is more opportunity for nutes to build up in the soil. I am using the General Hydroponics Simple waste to drain schedule, and I'm only doing them at half strength.
Has anyone else using LEDs had to back off of nutrients or tone them down a lot because of temperature issues?
