Can I bring her back?

Clone her and try again. I rerun things all the time. Everytime I get better and better results. But right now, I would say that she is early enough in flower, she will produce more pistils and still continue to produce for you. Also the smell should come back no matter what because she's barely even started producing mature trichomes. The smell you noticed may have been from the plant being burned by the lights.

Lay the branches by melting the stems, twisting the stem back using one hand and forth using the other hand , just keep on twisting back and forth until the stem starts to soften like if was melting. It won’t bring back the burned buds but at least it will save what is left.
