First time bearded dragon owner, I have Q’s about diet, poop, and lighting.

[Sunny lil dragon mom]

I’m so happy to have found this forum. I’ve been reading and watching lots of YouTube videos to try to make sure that I am giving my little bearded dragon the best care possible. I keep running into some conflicting information and I’m worried I might not be doing things correctly. I’m sorry if this isn’t proper forum etiquette or if my thread is way to long.
Any help/suggestions would be awesome!

My bearded dragon, Sunny is a 4-5 month old female. She’s just shy of 11inches in length and weighs 54grams. We got her in August when she was about 5 inches long.

The terrarium I’m using is the Thrive 40 gallon w/ front opening doors 36x18x18
(I have plans to build her a custom 4x2x4 out of a display case we have)
Hot side of tank temp range read with laser thermometer gun and digital probes: 100-110 on basking spot, 92-95 ambient temp on hot side w/23-30% humidity. Middle 80-89 Cool side: 78-85 ambient temp with 40-45% humidity.
at night temps drop down to 70-75 and humidity gets up to almost 50%

First Q: Lighting,
which UVB bulb is best for my 40gal 36x18x18?
For basking I have the Arcadia 100w basking bulb.
I bought the Reptisun T5 HO 24inch hood which came with a 5.0 bulb. I kept seeing everyone say the bulb to use is the 10.0, so I went out and bought one yesterday and installed it today. The hood sits on top of the mesh top and is positioned in front of the basking light (basking light is positioned in back corner above basking rock/hide) going down the length of the cage.
I tried to look up the distance from the bulb that is appropriate but the zoomed chart was a bit confusing. Sunny’s log at it’s closest point underneath the UVB is about 7inches and the tank is only 18 inches deep.
Is the T5 HO 10.0 too powerful for such a small enclosure? Should I go back down to the T5 HO 5.0?
She seems to like to lay at the 7inch depth on her log under the 10.0, it’s angled from one corner to the other so she has about 24 inches of log she can move up and down in varying height closer or further away from both her basking lamp and the UVB. If the UVB is too close to her, can I raise the UVB up off of the mesh top or would that cause too much UVB loss?
Also is 70 too low for night time when her lights go off? Should I consider buying a ceramic heat emitter? If yes, should it be same wattage or less so that temps don’t reach daytime levels?

Next Q: Diet
When we first got her she was a ferocious bug eater. She would go through 35-50 small crickets per day but would not touch her salad. The pet store we bought her from said that she would mainly eat crickets and not to worry if she didn’t eat any greens. Of course after researching online I found that she should be eating 80/20. It’s been really hard to get her to eat anything other than bugs. I’ve bought every vegetable on the safe to eat lists, bought bee pollen and so far the only thing she eats enthusiastically is butternut squash lol. So she’s like 98/2 right now. I give her a rotation of greens, mondays mustard greens, Tuesday’s turnip greens, Wednesday collard greens, I even tried a little bok choy w/them and some endive, she turns her nose up at them all. The only green she will even consider eating is turnip greens if I hand feed them to her and even then she only takes 2-3 bites and refuses any more than that. Other veggies she does like but aren’t staples is green, red, orange bell peppers, shredded carrots, and spaghetti squash. I bought an acorn squash today for her to try but I’m really wishing she’d eat more greens. Any tips for a super picky 4mo old or am I panicking to much and should just continue letting her nibble and enjoy her butternut squash every day? As for protein I’m weening her off crickets as a staple and trying to move her onto Dubai roaches and BSFL. The bsfl haven’t arrived yet but she’s eating the Dubai’s ok. She still gets super excited and comes to the glass when she sees the cricket container come out. The Dubai’s she just kinda watches them crawl in her little dish for awhile before she decides to eat them. I’ve been feeding her twice a day, about 10 small Dubai’s or 5 medium per feeding.
i was dusting both her feedings until yesterday when I seen someone else mention that they should only get supplements dusted on one feeding. So now I’m doing Rep Cal w/D3 5 days per week and Herptivite 2 days per week. Alternating them. So like 2 days of calci w/d3 then one day with herptivite, and so on.
that was the recommendation for Juve’s that I read on Josh’sfrogs when I purchased the supplements. Is that an ok regimen for supplement? Should I be doing a calcium w/o d3 on some of those days?

And my last question which I know from reading lots of threads, is a common one but there were a few questions I couldn’t find the answers to in them.
Qoop, should I have it tested?
When I first got her she pooped once per day a small brown log with semi hard white urate. Very dry, no smell. That changed about a week and a half ago, around the time that I had to go buy crickets from petco because my online cricket order got delayed due to hurricane. At that same time is when I first introduced dubias. Since then her stools have become much more watery, and less log and more pile, and she’s pooping 2-3 times per day. Her urate is still white but there is also a thin slimy whitish film on her poop now and a noticeable foul smell. Though the smell doesn’t fill the room, it’s noticeable when I open her cage after she does her routine morning poop. Her 3rd poop in the evenings is often very small mostly white, very watery. I don’t have an exotic vet anywhere near me and the one that is closest (an hrs drive) is booked out by a few months. Should I just wait since she’s eating normally and no other signs of distress or would it be good to buy one of those online parasite tests? Are they reliable?
I don’t want to risk her having parasite levels get to high while waiting months for a vet appointment.
also I did see that watery but formed poop is a sign of being well hydrated and is normal, is that the case?

thanks so much in advance, I’m so excited to have this sweet little girl. She’s already such a character.
I went ahead and attached a few (ok a lot) of pictures taken today.
