Nutrient suggestions

I am currently growing ak 48, maui wowie, grapefruit, and bubblegum in a dwc system in a 5x5 tent with a 1k watt light. I have been vegging for 3 weeks now and am about to flower next week. I am using the flora duo GH nutrients and was wondering if anyone had any other suggestions. I grew with just those nutes last grow and the plants turned out amazing.

I'm no fan of trying to fix what isn't broke. If it's working keep on truckin'

If you are just dying to try something new you can go mega cheap and use Maxibloom from GH from start to finish. Worked great for me over several years.
