Blueberry Fem. Problem

Please help this newbie identify what the issue is with my Blueberry Fem, the leaves are turning light green. For some reason the pics arent showing up for me in the sticky post above. Any help is appreciated. Thank you

Either your pH is too high or you need a little epsome I think.

Looks like Calcium\ Magnesium deficiency.
Are you using coco or soil?

Thank you for the replys

I am in soil, use ocean forest. I use about a teaspon per watering of GH Maxi grow powder (just flipped the lights last night), probably dont give it straight water as often as I should and set the ph between 6.3 to 6.7 or so.

check the ppm of your soil runoff. You may not even need to add nutes
