Cant figure this out!

I have 9 plants vegging in a 4x4 room with a 600w hps. medium is canna coco and i have recently changed to canna nutes as i was getting very slow growth with the nutes i was using even when using the correct ph. They are getting watered and fed once a day as the canna instructions say to.
They were about 6 weeks into veg and started getting patchy yellow new growth and now the new leaves are looking a little irregular.

When i changed nutes i found that the canna coco nutes set the ph to around 5.8 so i just left it even though i was feeding them at 6.2 with the old nutes, so at first i thought this may have been a ph fluctuation problem so i upped the ph and this seems to have made no differece, so im thinking its a deficiency of some sort but i have no idea what?

Please help!! :)

just because canna said feed every day dosnt mean you feed every day or maybe even at the level you are using how much nutes are you using mate per ltr of water ?
 
sweet sounds simple

Can you please explain a little more so i know where i went wrong?

are the nutes being locked out because of the to many salts in the medium or because of the ph?
 
Your probaly running your nutes to high keep your ph to 5.8 . what level you running your nutes at per ltr ?
 
cut down on the nutes after the flush a touch let the girls recover , your looking for dark green plants which is a basic rule of thumb
