My caution would be if you are still adding ammonia. This might kill some plants (ammonia is toxic to plants, fish and some bacteria at high levels). Might also get into the wood.
As you are along the cycling road, I wold continue and add the plants and wood when the tank is cycled.
For the future, as I would not change horses mid-stream: Another method that I always use is the so-called "silent cycle," where the tank is set up with live plants and the decor and when running the first fish are added. Plants need nitrogen and they take up ammonia/ammonium faster than the bacteria so the tank cycles slowly and minimally, thus "silent." There is no harm to fish with this, and you cannot detect ammonia or nitrite along the way with test kits. Provided you have a good planting, including some fast-growing species, and the first fish are few, this works very well.
