1000W HPS (One of the good brand .. Paid 85$ for it at the Hydro shop)

I did not have time to flush them last night so I will do it this comming sunday and yes, my tap water is 6.7 PH.

I know everyone seems to think 6.3 is too low for a soil grow but what can I say, thats what they recomend for soil at advanced nutrient : Nutrients | General Hydroponics | Hydroponic Fertilizer Supplies

Will let you know sunday how it went ... Still, they look like the needed more food as they where all geting so pale so I feed them last night. If they look like they are having a hard time tonight or saturday, I will flush right away !

Thanks for everything
