White Shark Mother. Question about Nutrients. 1st Grow.

[Rocky Balboa]

Im new. First Hydroponic grow. I have a question about nutrients. I am running a hydroponic 4X4 flood table. I am using DNF A+B formula & have a tri-meter in place. I was given this White Shark Mother plant which I posted pictures of it in the gallery or something but am uncertain about how much nutrients to add. My tri meter reads 90 is that enough? Can anyone possibly help me. Thanks

Re: How much nutrients do I use?

Here are my pictures of my white shark mother.

Hydroponic Grow: Is it better to add nurtients at a weak solution such as 50 ml of A+B formula which is 900EC on my tri meter. I am using the DNF Formula & my booklet says for mother plants it should be 1600EC so im kinda confused. Are you supposed to half the nutrients or something? Someone please help. Thanks
