Hey KaylasKush
I'm UK based & have been using Maxibloom for some time. I couldn't find a local shop stocking this so bought it off *bay & had it imported from Europe. Cost about £30 all in from memory. I tried Maxibloom based on the numerous threads online about the KISS method with Maxibloom.
Long & short is that even though this is classed as a bloom nutrient it has enough N for veg as well so its a simple one part feed for the entire life cycle. I've used it now on my last 5 grows, 3 plants at a time & still have some left. The only addition you may need to this is some calmag depending on the substrate & strain you are growing.
When I run out I am going to try a UK based powdered fertilizer I came across. The below link is for a recent thread on RIU where a site member details using Solufeed & calcinit. There is a mention of another fertilizer towards the bottom of that thread so there are 2 options there. Both of these options would be 2 part powdered fertilizers where as Maxibloom is a 1 part.
Maxibloom has given me great results so far & is cheap & easy. You can't go wrong really. I will be trying one of the powdered fertilizers mentioned in the thread below quite soon. Though they are 2 part formula's (i.e. a little trickier to dial in) they when bought in bulk represent the best value nutrients available in the UK.
Hope that helps.
