I ve got 2 Pineapple chunk they are growing fine and I need to flip them to 12/12 but I have some yellowing on one which I cant get rid of. One plant is indica dominant and it is fine the other has more sativa dom and has yellowing leaves which wont go away.

You're locking out Ca and Mg, Bud... bring the root-zone to 6.5/6.8 for improvement. Observe below: http://boards.cannabis.com/attachments/plant-problems/281235d1325194867-brown-spots-some-twisted-leaves-some-tips-curled-down-phchart.jpg
After reading your advice for rinodank I was planning on flushing with 7.0 tap water, and maybe add a little dolomite lime. My tap water is about 8 out of the hose can I just use that to flush till I get to 6.5 ? or is that to drastic a change ? Thanks mmman
Yea, man... flush with that, it'll be perfect, wait and see. Simply run that through and check the run-off immediately as the first water runs through, and adjust from there. You'll probably be able to bring her right back to where she needs to be. Then, after this flush, move to further correction if the need arises with the next water through after she dries.
Easy on the ferts. Please read in it's entirety. http://www.mandalaseeds.com/Guides/Fertilizing-Smart-Guide
