coco

Hey guys, I'm growing in coco & just bought coco A & B nutrient. Has anyone else used this & do I use their recommended dose which is 1.9ml per litre or be cautious & use half of this?
A little info; Royal Queen seeds
Strain; Critical.
3 wks old & on its fifth set of true leaves.
All help duly appreciated..

I'd start out at 1/2 strength or even 1/4 strength with those nutes, I've heard of them used on this site before so I think they are respectable nutes.
