Thx, some of the symptoms is there!

Spreading to all my girls now, small rusty spots on almost every leaf! does not look good!
Though it was PH at first but runoff was good, so did a flush on the worst and it only got worse. Sucks :S:S

Whats a 'good runoff'? What was your number? Low pH in soil can cause P deficiency pretty easily from my experiences.

Runoff was PH 6.3.

But you think i should add some P to it? Have some more pictures in my journal.

Thx for looking into it, really need some help here!
