Is this calcium?? Deficency

It's really hard to tell . New leaves are turning yellow . And some of the new leavs are also really leanthy and skinny ... Light green . And some are getting twisted and fried .

I just need a few more answers , how are they looking , and what should I do . I added 5ml per gallon for the cal-mag about two days ago should I cutt off the infected leaves should I leave them on ? Will it effect the flowering of the plants ? Anyone's response will be really appreciated !!
