Alright guys ... I have a problem , done loads a researching and cant narrow it down sufficiently to treat .. photos to follow ... Basically i went to water/feed the twins who are into 2nd week of flowering , came home to see yellowing on some of the top fan leaves ( SEE PIC ) of my northern lights auto...red russian xxl not affected
..... grown in soil .. fed every 2 days as required 1.5 lts ( Just over an american quart )
PH .. 6.3 _6.8 .. checked run off at 5.8
12/12 , 600w light ..light 3ft away from top
I also use a speciality bloomer , super pk (see photo) , I do not use it every feed as it is NPK = 0-20-25 ... im hoping this could be my problem but not sure ..
Any help would be appreciated
