Depending on how big your bucket is, how many holes you have in it etc. then drying times and how often you water can vary. You might get a little droopy from over watering, but its better than nute burn.
What type of soil did you switch from? Your plant may have just been going through a little shock and adjusting to new soil. Fox farms is supposed to be ph'd; I add a little dolomite lime to mine just to make sure there is plenty of calcium and magnesium for the plant, and it also helps buffer the pH of the soil BC my nutes make it LOW.
I have heard tons of people on here say fox farms is too hot to start growing seeds in, but have tested the theory myself and haven't had any problems. Your plant should thrive in it.
