Hey chaps, I've got a really useful chart in my grow room that details ph and feeding patterns. I'l try and post a pic of it tomorrow. If ph is dropping while ppm are also dropping it could be you are giving them slightly to much food. I say "slightly" as your plants look great and the ph only dropped to 5.5 which is still In the optimal range for hydro. Let them feed for a day or so without adding more nutes to see if that stops your ph dropping out. I've read in a few journals people running rdwc having problems with roots blocking pipes, if you go on my thread and read Scrogdawgs latest journal he'd be a wealth of knowledge for you as what he doesn't know about rdwc isn't worth knowing. He's just put his clones in his system so he's not far behind you.
