Stunted growth

Hi, she is like this for 2 weeks now, not doing anything, I was using base Advanced nutrients from start and I just flushed on monday with ph 6.5 water to see if it would help but I don't see any progress.
New leaves still show deficiency. Wondering if I should add another dose of nutes or just wait a little longer.
Its 2 months in flowering atm, temps and humidity are ok and strain is Purple Queen.

hard to tell, could be Potassium, calcium.. not entirely sure

What are you feeding exactly? What medium are you growing in?

2 months into flowering = @ 8 weeks. You mention it's still putting out new leaves, so it must still be growing to a point. In the same breath, it has to be close to finishing I would think. What is it exactly that you're hoping it does? You definitely have some deficiencies, but you're too far to the end to do much in fixing them. I'd ride out the grow until the end, take your notes and make corrections for your next grow.
