L,
I can only echo what has been said above.
Supplemented the fert strips last year with Fox Farms liquid Ferts, which is a good product as well.
No fert strips this year and relied completely on liquid Ferts, prinarily Urban Farms TTF both down the tube and as a top drench. Worked great.
Definitely pick a product with less N at this point. You should find both Fox Farms and FloraNova at the local hydro shop. Urban Farms you would need to order on the web.
