Thanks man, I just added the second row of the net to the right side and gave them a good soak as the water is taking 25mins to fill up a 10l bucket lol, they wont get any water until a loooong time now lol.

Ive never really wrapped my head around the ph properly but I see there was a post on it in the science post thing :)
hahaha all I know is that they get a nute lock out and don't do anything if they don't have the right ph.. and in the past I thought and still think up until you saying this that it was due to that.. lol.. Is it now continual heat where you are now also?!
