I am watering them weekly with Dr. Earth's Vegetables/Flowers Bloom powder concentrate. 1/2 cup to 1 gal split between 2 plants in 5 gal pots. I fill it up and let it soak overnight to get the fertilizer good and soaked, then shake and pour the next morning (24 hours). They love it. If I get any signs of burn I just add about 1/2 gal of water.
