if it is still in veg imo you should be fine. if in flowering that is all up to you. i did it in flowering they grew back just fine. you pretty much slow the growth down and will take time to recover from the stress. just my 2c. i say this because people always say oh your going to fuck up your yields, etc.. but tbh everything you do can fuck up your yields. water temps, nutrients, temps, humidity, etc..
