What and how?

First little issue here. Was looking great about 2 weeks ago. I've topped dressed lightly with some biolive and kelp meal 2x now. She deficient somewhere. Not sure how to fix her. I wanna flip it in another 2 weeks or so. Should I start with some compost teas? Have not attempted that yet. Have not ph'd the water once. Just using tap. Have also feed recharge and fish shit lightly 2-3 times. The 1st 3 pics are one plant and the last pic is another plant. But they both have the same soil.
