Will I be able to eat those tomatoes ??

[spadekevin]

Hello,

I built an hydroponic system just to try and one of the tomatoes grew pretty well (see photos).

As some fruits are starting to show up, I'm wondering how safe they will be, provided that all nutrients the plant ever received came from water mixed with the most basic liquid fertilizer I could find, a green universal stuff with a 5-2-2.5 NPK (you can see the composition in German, French and Italian on the bottle, it's pretty straightforward).

Will I be able to eat those tomatoes or will I just die?

Another thing: should I try to change the NPK now?

Please help.

I didn't find the right solution from the internet.
