a month and still no flowers,
 

I've just started experimenting w/ hydroponics. I planted tomatoes in a bucket drip system, tomatoes grew like mad. It has put on quite a few buds but hasn't flowered yet. The buds have been on for quite some time, over a month and still no flowers, while the tomatoes in my garden have flowers and also small tomatoes on them. am using mirical gro and epsom salt. what's going on???

You need to add some calcium nitrate to that and adjust your pH between 5.7 - 6.1
