plant magic old timers organics

hi. after a coco grow I'm back to using soil again but rather than special mix I've gone for bat mix and rather than go back to bio bizz nutes as pervious I thought about using the plant magic old timers organic range.
just wondering if any/many have used this range of nutrients.
the range I'd be using would be:-
GROW
plant magic old timers organic grow 5-3-3
plant magic veg boost
plant magic granules
plant magic old timers magnesium
BLOOM
plant magic old timer organic bloom 3-5-4
plant magic biowetter
plant magic organic pk 4-8
plant magic old timers magnesium

hurd good things about plant magic from my local grow store so I've decided to give it a go. any advise or comments if you've used it welcome
