600w mh/hps grow - DPK - 1st dwc run

Hi Guys,

First time posting on this forum, and its also my first dwc grow. I'm using 2 Part Sensi Grow at 1ml/L and PH Down to 6. I currently have it under a 600w MH at 24hr on.

I'm seeing some burning around the edges and not sure whats causing it. The nutes are at 1/4 strength, I was planning on running 1/4 nutes for the first week, then pick it up there.

I checked the PH and it was up to 7 so I brought it back to 6.

Any suggestions would be great.

Thanks

5.8 is a number I hear hydro growers say is ideal. Maybe some ph damage?

Thanks I hope thats the case also, I've since dimmed the light to 50%. going to take it easy on her.

Are you using pH perfect? What about your water?
