I’m in week 6 of flowering and over the last week I’ve seen the leaf tips turn yellow and now they’re spotty.
I’m feeding them Foop nutrients based of their recommendations, but this week I dialed it back by half because of the leaf issues.
Is this nutrient burn? What are the steps I need to take to make sure it doesn’t continue?
Thanks a lot in advance for your help!

Might be a potassium deficiency.

Welcome to the forum! 
While agreeing with others here, I would also check the height of your lights. The tops are curling up and with the upper part of the plants looking yellow can mean light too close or too intense.
Good luck! 
Pot Ash ium looking to me as well
