I'm a frickin idjet..First I want to say I have identified a huge problem with this here interwebs..Instead of running to someone for the answers. All I needed to do was smoke a joint and take a look at things...Well one of my mister heads was out.. So with the pump nocked off kilter a tad and one if the four heads dead stopped the whole row in the front got way to dry.. Thank God I had a whole stack of pipe dream pieces to scavenge a new head from..I'm sure I'll need to make a few adjustments before the next run.. And there will probably be some dry spots and death on this run..Ohh well we live and we learn..
