Am i missing anything)?

A couple of weeks on... tds ranges from 140 to 170 come water change (once a week).

Plant growth remains very slow but yesterday I upped the light strength abit to try and improve this.

Took a picture of rotala, this is now just below the surface but I'm unsure if the veining is normal or you would say its deficient in something?
