New Grower First Grow: Think Different in hydro under HPS

oh and i forgot to mention, the light has been running at 400 watts for 20hrs on 4hrs off. When should i turn it up to 600 watts?

Wait until it shows sex then give her all the light you can imo if you use 600 now it's just wasting light and power. Just make sure to pull light away when you turn it up. I run at super lumens 1250 watts and have them 14'' away but that's because I have very good air flow through the hoods. Just hold the back of your hand at the top of the plant and if it feels hot after a few seconds then move it up a little more. at 600watts your should be good at 12-18 inches.
 
Thanks newbud, yeah its just the one plant she popped her head out of the rockwool on the 1st so shes only 5 days old. I'll post a picture here in a tit. Glad to have you along! :smokebuds:
 
Thanks for the info TD, you're fuckin awesome! Our light is a 1000 watt so well probably just turn it straight up to 1000 after it shows sex.
 
Here's the pic of the plant from today. 5 days old!

Just cleaned the reservoir and fed plant . After putting the extra oxidizer in there was a lot less nutrient buildup at the bottom of the bucket. Dab time:dancer: :hump: -maurisa
