hi im new here i was hopeing someone can help me out.i have grown pot a few times in the past but this problem has never came up i have 7 plants with only 4 big ass pots. two plants in each of the three pots one in the last one. i know what your thinking (ones a male and ones a female) no the problem is i cant get the ones that are togeather to bud. i have been flowering for like three weeks. the one in the pot by itself is budding all over. but the ones that are togeather have not even one sign of flowering yet. they are all in the same room. the same darkness . can someone please help me . or explain to me what is going on. thank you

put all your plants in one plant per bucket

the plants that are doubled up need to be hit with the bloom more offten. for exaple single pot plants get 1 gal. bloom feed then you need to give the doubled up pots 2 gal.

When you plant two plants in one pot sometimes a phenominon called scissoring happens which takes priority over flowering:
