This is my first time growing Autos so my knowledge here is non-existent. The thing is that I want to make my own feminized seeds with STS spray on some HulkBerry Auto, BUT. My ladies which are about 3 weeks old (since germinated) and are 30cm or12inches have already started flowering. My big question is whether it is too late to use the STS and reversing a female now? Considering that they are already flowering. I would be extremely thankful for some help/tips on what to do.
