Small Budding Problem Please Comment

I have two plants both 30 days into flowering one is a black berry and the other is a tangerine dream. My question is they have bothe been flowering for 30 days as of today and the tangerine dream plant is hardly budding compared to the black berry plant the black berry plants buds are good size and the other one is hardly budding it has lots of white hairs but thats it they are both grown in 3 gallon pots in soil and are half way done with flowering is there something i can do or is this normal i believe the tangerine dream is a mostly sativa dominant plant and the other is mostly indica . I have mostly grown all indica strains in the past this is the first sativa.............Any advice would be appreciated. they are both fertilized with a 15-30-15 fert

Some plants tend to grow at a slower rate then other plants. It sounds like the tangerine will take longer to be harvested then the blackberry

The buds on the tangerine are way small compared to the blackberry and to me dont seem to be growing at all.

well it could be one is sativa and one is indica or predominantly one or the other sativa has long thin leaves and the indica are fat broader leaves

oops didnt put the main point sativa has a longer budding cylce than indica
