Yeah those are no good for plants. 10k is really high. You can use 10k but you need to add co2 and ferts for proper growth. Even then I recommend lowering it to a 6700k bulb. Actinic is pointless for plants. It does nothing for them
I'm sorry, but simply none of this is true.
Actinics, and to a lesser extent 10k bulbs, are heavy in the blue spectrum of light, whereas a 6700K bulb is more balances and the <4000K bulbs are more red heavy. Plants can use pretty much
all visible light plus some invisible light, although the reflect much of the green/red spectrum. This means that they prefer red/blue light. So why, I keep asking, are actinics 'pointless for plants' if they are perfectly capable of utilizing blue light? The answer is that this factoid is incorrect. Plants can and do use blue light. That being said, blue light should be avoided in FW tanks simply because it makes the tanks look surreal and fake, which is generally counterproductive to the goals of a planted tank. Many people will use a 10000K/6700K combination of bulbs to achieve a desirable appearance.
You do not need CO2. I would consider looking into Excel and another fertilizer such as the Flourish line, but if all you have is anubias, then it's really not going to be a problem until at least payday, in which case I would only recommend Flourish unless you want to get (or already have) more plants.
Bad spectrum bulbs will NOT 'melt plants'. Something's happening in the tank that needs to be addressed. Anubias is one of the most low light tolerant species out there, so it's almost certainly not related to light levels or spectrum. The fact that it started happening in a matter of hours is worrisome though.
Could the plants have gotten too dry at some point?
What's the temperature in the tank?
Can you take some pictures and upload them so we can see the damage?
It's very possible that they were just roughed up in transit or need to adjust to your tank first. Anubias are extremely hardy plants, so they'll probably bounce back soon.
