Seems a reasonable approach to me.

Anyone dose throught their top-up?

Are you using the auto top up to actually top up or are you putting it onto an on/off timer to pump an amount of ferts in?
I only ask as if using as a top up your rates of evaporation could greatly vary and this will effect dosing. You'd really need a fairly constant measureable rate of top up to know you were adding enough ferts. You'd be better off with a designated dosing system or just sticking with manual introduction IMO. Dosing ferts doesn't have to be a precise art but you do need to ensure your adding enough regularly.

Good point - I will start manually (IF nothing else, to learn what I am doing), and see how much RO the topup is putting in each week, and how consistent it is. I am in London, so my water will be 'pre-loaded' with a fair amount of nutrients, and I will also be using TMC soil, so will have a certain amount of 'buffer' if I underdose. From what I read, overdosing is next to impossible?
