they look good. Watering once a day is enough. They like good drainage and airy soil. Overwatering causes slower growth. If you don't mind spending a few bucks goto the store and buy some good organic fert to give them. Alaskin Fish emulsion works great for me. I use 2 tbsp per gallon. 5-1-1 through veg when my pre-flowers showed i started useing a tbsp of the 0-10-10 and a tbsp of 5-1-1. When they get further into the flower stage I will only being giveing them 0-10-10. Also my plants are in the ground so your measurments might be different read the label. Oh yea i feed them with it once a week. One more thing if you were not already thinking it, I would put those in some bigger pots 5gallon buckets with holes in the bottom works the best. Happy growing
