You can do it, but it's not worth it. Hesi is a mineral fertilizer, which isn't good for the soil life. The soil life needs organic fertilizer, but it can't work as well now since the soil life isn't optimal anymore. Also, organic fertilizer takes longer to take effect, so if you want to harvest in 2 weeks, the organic fertilizer won't be able to do much. I would just wait the 2 weeks; not much will change anyway. Good luck! 👌
