best nutes for soil?

So Im pretty sure my plants starting to show signs of preflower now Im going to start looking into getting nutes for her n adding sum better lights. What would you recommend for soil?

bio bizz. about £10 per litre. you only need the veg and bloom. if u want to spend more cash then thats fine but its a basic organic nute and its idiot proof to work with( trust me me im a fucking idiot), halfway thru flower buy a tin of mollasses(or if ur in the UK treacle) mix with sum boiling water and just add to your feed. simple as fuck. ive used it for a few years with soil grows and pull onaverage 3oz per plant, bonus is that its very simple to use and its bloody hard to damage your plants.
