Drip feed tomato feed capsules - good idea?

[PrideRavyn]

I saw some of these in the garden centre and bought them, as I am absolutely useless at remembering when to feed, when I last fed them, etc etc and thought these might be a good solution. They are just little bottles of feed that you stick upside down in the soil and it drip feeds the tomato plant for 2 weeks.

Is this ok, or is a rookie mistake again

i got some of these too so I would be interested in the answer. I also cut the tops of and stuck them right in when they where finished so the roots get more water by filling them(if that makes sense) I reckon as long as the stuff insode if ok then they should be fine. I wonder if tomorite do their own.
