That plant had been stunted. It isn't flowering optimally, so YES, could flower 16 weeks to finish and ripen. It has at LEAST 2 weeks of recovery and 2-4 weeks of healthy flowering to go. But with the mildew as advanced as it is, recovery isn't something I see happening. Sometimes pride can cloud one's vision to the point that reality is secondary. I understand you love your plant, but those buds are shot. Once again, I hope you aren't planning of sharing/selling and I wish your lungs the best if you decide to smoke mildew.
