Help ASAP

My plants are in the 1st week of 12/12 and I placed a small dehumidifier in my metre by a metre tent as RH was 64% after watering, I realised this morning 4 hours after lights were off that the dehumidifier has a small LED to say it’s on so quickly pulled plug with out opening tent, can this revert my plants back to veg and if so how do I fix it? Any help would be appreciated
