yep - i don't know what the drainage looks like under the bucket, but you want enough to where water can run out if it's just sitting. In 5 gal buckets I drill 3/8 holes around the bottom. Without these, you could be waterlogging the bottom of the pot. The biggest problems in peat is either putting down too much water, which gives you soggy bottoms, or not putting down enough water, which gives you a stratification layer in the middle of the pot. I'd drill some more holes in your buckets and give her a nice flush for your next watering, and wait to water until the top 2 inches of peat are pretty dry. If the top 2 inches of peat are dried out and the pots still feel like there's still a good amount of water in them, you're putting down too much and don't have adequate drainage. If the pot feels light before the top is dried out, you need to put down more water.
one thing I've noticed with peat is that it's extremely forgiving when it comes to nutrients. I try out different nutrients in peat all the time and have yet to see a deficiency in peat, but there's definitely a learning curve in figuring out how to water it.
