a couple of other things you will run into with led is
1. they run much cooler than HPS so be prepared for way cooler temps
2. the plants will use less water (probably a result of cooler temps)

The other thing your going to run into with LED.... less yield. If yield is not a concern then more power to you, cheaper to run and less heat.

why would you go to led if you get less yeild, that's taking one step back, i don't understand the point in them now??

First, it's not all LEDs...

it's the Blue/Red dominant LED panels at fault

A lot of us learned this a long time ago and have switched white dominant panels

It took me a while to get dialed in to my LED vs CFL. Mostly, as pointed out, due to diff in heat. That also impacts RH because less moisture gets burned out by the lights. I runa dehumidifier in my outer room now for that.

My biggest challenge was it taking too long for the pots to dry out. My soil drains very well and it hit me still. I have since drilled holes in the sides of my pots. I also keep them on some cooke cutter to allow some airflow into the bottom holes. That took care of it.

My light is white with red in flower (A51 SGS160). I don't really find I need more CalMag.
