I disagree on the Ph pen, your growing outside with this being your first good grow. Don't over think shit. If you were indoor i might say yeah, but lets get through this outdoor first:thumbsup:

Just start nutes at 1/4, then build up on them. And make sure you water in between adding nutes. You dont want any build up of them in the ground and in less your the weather dude, cuz ya never know if its going to rain, which will wash some nutes into the ground.

Keep er grreen bro:hippy:
