You'll most likely have tons on blue for the plants, but very little red unless you get something closer to 2700-3000 Kelvin. That's the downside to LEDs, too much blue and no red. You generally have to add red LEDs to get the spectrum needed for growing plants.
It is a 5000k bulb. I was trying to get as close to 6500k as I could. I thought 6500k was what you wanted for plants. I was thinking back to my SW days when 6500k MH bulbs were the go to for refugiums and I thought planted tanks. HD had bulbs that were around the 3000k. I'll give the 5000k a shot and if I don't see good growth I'll try a 3000k.
Im planning on java fern, anubis, red wendetti( if I can find it), and then a taller background plant that I haven't picked out yet.

LED are a completely different game.
Before, you needed the higher Kelvin rating to get the blue light out of a fluorescent. Since all white LEDs are actually blue LEDs with phosphor, you get bleed through of the blue. With lower Kelvin ratings, you get some red due to the phosphor having red content to create the "warm" glow.
Fluorescents and halogens have a broader spectrum, with blue, green and red spectrum. LEDs are very specific on color, you get what you ask for and only what you ask for.

some do a mixture of 3000K, 4000K, & 5000K until they find what works and is pleasing to the eye.
