Please Help bud same size

I have some purple diesel and they're 5 feet tall and 5 feet wide and it's been flowering for a month and the bud is still the same size it's not nugging up like my other plants and I don't know why. I'm feeding them Sensi A and B bloom and grow more blue powder 0-50-30.

it might blow up a bit later, but thats pretty beefy bro, at least 2 pounds IMO

They don't double in size til after week four.

Jim Jones if it's to be cut and dry now i'm thinking after it drys it'll be like the size of a finger nail because it's fluffy and not forming into colas.It's been at least 4 weeks. If thy nug up than yeah it might be a good harvest. It says 9 to 10 weeks till it's done. I always think that if the hair is turning brow than it's about to be done if that's not the case than I wouldn't bee so worry.

i have had plants hairs turn 100% brown 4 weeks in, nowhere near done. took 5 more weeks to finish.

give it time.

I think it's more like week 6 now because my other strain flowered first about 2 weeks in and then these started to flower. My cherry pie is ready and will be harvest this weekend.
