Curing Magnesium Deficiency in Cannabis - RQS Blog
Micronutrient deficiencies are avoidable and in the worst case scenario, very treatable. Magnesium deficiency is a common problem. Here’s how to solve it.

Looks like light bleaching more than any deficiency. Low Mg is going to show on lower, older fan leaves first. Being a mobile nutrient the plant will steal it from older leaves to keep the tops healthy.
Raise your lights. LED I presume? Tho HID lights fry top leaves too if too close.

I just dimmed my led to half power, flushed the system, and put in all fresh nutrients with 1/4 tsp of Epsom salts per gallon.

As long as the actual grow tips aren't damaged then the plant will grow as normal. The damaged leaves won't get any better tho but it won't hurt to leave them on and they can still make food for the plants as long as they have green left.
Not sure why you would flush the system tho. Light bleaching is not a nute issue.

You can clip them so plant will not waste time trying to repair them.
