Pereskiopsis yellowing, slow growth

I'm attempting to grow pereskiopsis indoors under a Quantum board type LED grow light rated at 150 watts.
Picture link
As you can see I'm having a lot of trouble. The healthy green growth at the very base of the pereskiopsis is from a rooted cutting. The skinny section represents a few months of new growth under the grow lights. The lower leaves consistently yellow and fall off, and the thickness of the new growth is terrible.
Lights are set to a 14 hour cycle about 18" away from top of the plant at about 50% power. I've been watering 3-4 times a week, but over the past few weeks I've cut back to 1 day a week because someone suggested I may be overwatering. It hasn't made a difference. I've also been fertilizing for the past 4-6 weeks, also made no difference.
Any ideas on what I'm doing wrong?

yeah what kind of soil mix you got there, maybe too much water, and don't fertilize them
i think they want some sun, clearly the tops aren't showing any growth
when they are healthy they will bloat up some more and the leaves will be more rigid, and the tops will have upward pointing leaves with bright green healthy color

I'm using regular potting soil without any additives like perlite, etc. Really, more sun? I figured this grow light would be more than sufficient. Under the same light I have some trichocereus seedlings that are growing very nicely, healthy green and fattening up after only 4 months from seed.

A whole lot more sun. I grow mine outside in a mix of part shade, and full 12+ hour scorching sunlight. It's a sun plant but can grow in windows.

Wow, that's surprising. Hypothetically if I wanted to grow this indoors -- I don't, this is impractical -- what kind of lighting would it need to thrive? Like a 240 W quantum board or equivalent 600 W HPS?

It's normal for them to lose their lower leaves, just how it is. I'm gonna go against the grain and say that lighting isn't the issue. Your internodal distance is excellent (no elongation/stretching of the stem). What's the temperature in the room? Pereskiopsis strongly prefers higher temperatures. Anything less than 80F and the growth rate suffers. just my 2 cent tho.
-------------------- Thank you for taking the time to read this message. Have a wonderful day.

About 72-74 F in the day, 70-72 F overnight.

This is a nutrient related issue. Leaves will die off due to cold, sure, but i doubt comfortable temps will do this. I prefer to keep pereskiopsis in lower light conditions so they don't put out giant thorns. Assuming you want these for grafting, its often good to let them etiolate a bit and the stems to thin.
Look at the redness of the stem, look at how even the new growth is more yellow green than straight green.
Mobile nutrients get taken from older leaf growth to sustain new growth. Which nutrient is responsible is hard to say due to coloration being blown out.
Water with seaweed kelp extract, and a light (1/4 recommended) dose of something with a decent amount of NPK. You should see a difference within 3 days

What's your watering frequency like? I was fertilizing with Schultz Cactus Plus 2-7-7 (diluting it 2 droppers per gallon of water.) It didn't seem to help any, but I can try it again with a different concentration of fertilizer.

Well my watering frequency will not equate to your watering frequency unless our soil mix, rh, temps, etc are all exactly alike. The red stems and coloration of your plant remind me of N deficiencies (leaf color and the tips look lighter... at least from my house), as well as micronutrient def (stems). If it was me I would probably follow the higher concentration instructions for at least 1 feeding, and get some kelp extract for micronutrients and trace minerals.
I water 1-2 times a week, and I feed when I need to, but have a fair amount of perlite in my soil.

Sorry for the low quality picture, here's some new photos without HDR and with lighting more representative of real life.

Yes, I think the new growth did try to root (those dangling tongue-like things) but these runners haven't grown in a while. The new growth has a slight red tinge and looks kind of woody, although the newest new growth appears greener and healthier.
I'm going to try more fertilizer and see if that works. Thanks.
