Hi! I have Durban Poison, Holland's Hope and Puple White Widow strains planted in a crowded bunch (total 15). The Durban Poisons and Holland's Hopes have not even showed their sexes yet, however the Puple White Widows have been flowering for about 7 weeks. Are there any chemicals / fertilizers out there to induce budding for the Durban Poisons and Holland's Hopes? Also, would addig chemicals now affect the quality of the Puple White Widows as they are so close to harvest? I appriciate any help!
