If you bought a bucket with a netpot lid, I would assume its a 5 gallon bucket, that only holds 3 or so gallons of water up to just below the netpot. Sure it will work fine for awhile, with a smaller plant. But after a month and she gets bigger, she'll eat, drink, and even expel waste back into the water so fast that that small capacity cant keep stabilized. Your EC and ph will fluctuate all over the place and youll be dealing with lockouts and other problems like the roots drying out. Eventually can lead to root rot. i bet if you cut open the stalk you would find a blackish vein like streak going up the middle of it, starting from the roots.
What you need is a larger container for a single plant. Hopefully at least a 20 gallon tote that holds 4-5 times as much solution as a bucket. The more solution you can hold the more it will stay buffered and more you'll be able to keep control over all the parameters.
A plant after a month of growth in a single 5 gal bucket will need res changes practically every day especially in flower, if not twice a day.
