first ever grow.. so cal..

what up, this is the first time i ever grew. (finally got medical). i have 5 nice size girls and 1 small bubba kush ( dont know what kind the others are). my question's are 1. can anyone tell me how much i might harvy? and 2. is this a sign of pre flowering, and if so should i start giving them some beastie bloom with the tiger bloom and big bloom all together? thanks for the input.

Damn I am regreting not vegging earlier, i also 6 babies outdoor here in CA, which i sprouted early june. You will for sure get atleast 1lb if properly done. When buds start forming us when u start with nutes.
