Last year I had two plants pre flower and start shooting one leaves. Recommendations were to toss and replace them.
I had no replacements so I left them. I am glad I did. They grew a great amount of bud that grew, lingered and then finished a couple weeks before the rest of the crop. The buds were great, dense and once trimmed unable to distinguish from other buds.
For me, getting an early finish was great. Good luck.
