Hey growdawg. That shipping is a bitch ain't it? Try not to fret, all will work out. A couple of days on that AF should be just fine. It's better to wait that long than mess up the progress you have made thus far by feeding them and not knowing the ph. So I would just wait on the trusty gadget that's on it's way. Are your photos the same age as your autos? Sorry I can't remember. I'm pretty sure they can start feeding about the same time but you'll still need that ph pen for their feed, too, of course.
