First time grower here , I have a plant that's getting close to needing a transplant. I want to transplant it from unknown potting mix to a coco coir and perlite mix. Is it possible to change medium half way through? If so would it damage my plant .

If you're still in veg, it will be fine if you can meet its watering needs.

Most potting mix is high in peatmoss, as such it retains a lot of water. Coco is the exact opposite, it doesnt retain water for very long.

With peat, you might have a salt build up issue if you dont water properly.

How big is the pot you're in, and big of a pot are you going in t
