Bubblegum auto 00seeds

Started from seed in 10l and took 11 weeks ,hit me off schedule ,as the hps lamp kept flickering off and on for a about 2/3 days would that stress and take longer,they got heat stressed as the light was too low for a while ,,would that cause budrot and the budsbeing airy and some bud not smelling ?other part of the plants are potent as hell!?
