I've got three tanks, one is a nursery for juvenile cichlids, so I'm not investing much in plants for that one, it would be a waste. I fertilize with Thrive in the 29, and Thrive S in the 5. I also have root tabs places throughout both tanks (just one in the 5), and use API CO2 booster liquid. Sometimes dose with Seachem Excel, but my respiratory system isn't a fan (I also have trouble being patient enough to do the math, for proper dosage in the small tank.) Have a nicrew light (the one that automatically links out with the word light/lights), on the 29. The 5g has some off brand cheap thing from the lfs. It does the job fine, but it was always just a starter. Below are photos of both tanks. The one with the flame sword is the 5g. People like pictures right, haha?
