Bloom's magic spells are consistent in names being related to a state of fire this counts both Ice Flame and White Flame. This rule allows Lava Jab and Volcanic Attack to work as well.
The only inconsistency she has with her powers is Season 4 with the misplaced Star spell called Supernova and the weird Arrow of Domino spell in Tynix form where did that come from Tynix has nothing to do with Arrows and there is no arrow shape to her fire spell if they wanted to do it correctly the spell should have been Diamondfire Arrow or Flaming Arrows.

There is an error in this video one of Aisha's permanent spells created and performed in Season 3 is mislabeled as Tecna's such as Underwater breath and it is so unnecessary to reexplain this when it was already explained in the previous Season of Season 3. It is my belief that by Aisha casting "The Under Water Breath Spell" is why the Winx dive without breathing or worry how to avoid the cold and the real reason why Sirenix develops a Winter transformation style, honestly because Aisha specifically says, "Yes, it turns water into oxygen and will also protect us from the cold." SamanthaKSSimpson up until this point of the show the cold bothered the Winx Club a lot including Bloom especially on the episode Mission to Domino. It also helps to explain in the Omega why the girls aren't frozen yet to death."

Now Tecna's spells Technoshock and Megawatt in Believix form fit Tecna's powers as does the laser cage and super prism, but her convergence join up with Musa in Purifying Wind how does Tecna help make a purifying wind? This isn't part of Tecna's powers.
Her Lovix special spell doesn't make sense either. "Chilled breath?!" really. What is that suppose to even do? It's like Stella's crystal winter. What are these suppose to even do?
At least with Tecna's Sophix her powers make sense in both versions Higher Order or Superior Order technology is used to create and keep order that is true in the Winx Club universe.
Bloom's and Flora's spells in Sophix and Lovix makes sense even if they aren't depicted well to show what they really do. And Stella's drop of light definitely makes sense in Sophix.
The other powers that don't make sense the way they are named for Sophix is Aisha's Vital Beat I hate this one because for her character having far fierce spells with even fiercer names this one feels like a cough out. And it even isn't giving her a new skill she is only repeating the same spell Tecna and Musa do anyways
I mean really come on Aisha's spells are
"Enchanted Plasma Wall which she used so strong against Sky and his dragon rider.

"Andros Hurricane!" "Morphix Tidal Wave" was so epic and fierce.
Spirit of Courage is very fierce too.
As his her convergence spell will Bloom, "Crystal Water" actually makes sense here.

Vital Beat sounds like it would suit Musa better than it does Aisha I get that people do see water as the vital beat of the universe but Universal Water's Strength would've been better and lived up to the fierceness of Aisha's other spells like Aisha's Iridescent Waves spells that she combined with Stella's Projecting Mirror Wavebeam that actually made sense one water does have its own slight glow and therefore can be seen as Iridescent and Water has always been part of Aisha's powers that never changes.
And giving Musa Vital Beat would give Musa a variety of names in her attack and defensive spells.
Musa's spells have gotten quite boring in Season 4 for some reason people keep reusing the words Sonic, Harmonic and Harmony in her new spells and that gets old so fast, Skylights. Vital Beat would actually be a spell that could not only affect the environment around her, but affect her internally finally trying to relieve her of where she has gone wrong because Musa contrary to her spells namedHarmony and Harmonic she isn't behaving Harmonically at all.
Musa's only interesting Spells are Magic Phase Boom (I know people think she was pronouncing a b for bass but it actually is a p being enunciated.) And Stereo Crash and the Raindance thing back in Season 2.

Very few of Tecna's Sirenix spells fit her powers except for her Logic Net.

Techno Punch and Techno Kick and Ditigal Strike are cool attack spells for Tecna in Sirenix as is Virtual Protection Shield which is weirdly called Neon Splice which makes no sense at all not even color wise. I like in this Season that Tecna uses her core knowledge of her powers and manifests it into the Logic Net normally we see her catch people with a laser cage or digital room so it is nice to a new spell finally being for the same purpose.
Genesis Blow makes no sense has nothing to do with her powers of technology nor does her special Sirenix spell either. "Aura of Sirenix?!" what does this even mean nobody ever explains it?! And Genesis Blow other name is the other version is worse "Biorhymthic Flow" that spells should be Flora's because Bio means green and life and it would give her a second fierce spell attack like Petal Hurricane and would make up to her later Season 6 spells Chlorophyll Bolt and Spring Shower that were just as fierce as her Venus Gobbler attack before gaining Enchantix."

At least with Season 6 Tecna's spell names make more sense.
One of Tecna's forgotten Charmix Spells is "Wire Beam!" There is so much more to use for Tecna's spells a spell Tecna should have kept using in Sirenix from her Believix power was her oil delete because when she uses Virtual Projection once she makes things Virtual with her magic she does have technology powers she does have access to the virtual reality trash can deleting system, Skylights.

While the Writers weren't doing their research and redoubling checking their work in Season 3 with the Fairydust rules and the Water Stars' delayed introduction scenes Nick was just not creative enough to come up with any creative names for spells on the spot or creative designs either. The Season 3 flaw instantly makes Aisha and Bloom look like they do all the hard acting work and it is not always fair to them for them to have to do all the work, Skylights, that is not the point of a team, my friends. At least Tecna got great spells in Harmonix spell and everybody complains how the X-Ray vision is incorrectly done but I don't think it is an actually X-Ray vision spell other than making Tecna's eyes see with gray scale I actually believe X-Ray vision is an X-Ray Insight Spell where she can see similar lengths beyond the dark spell but actually isn't seeing anything the way an X-Ray works I believe it is more of a I can see you/your problems from a very far away distance spell without her having to look too hard with her own eyes.
It is a lower form of her Megavision (I know it's not called that but this would have been a better name after all, Skylights, cause the other name slipped my mind) with her Mythix wand which she used to see what was happening outside that  was quite far away from Frank-stein's monster castle so there is a continuity there actually they use it once again.)

You can see in the video that Tecna's window of vision on Darcy is with a grey tint than beyond the bubble and where Darcy is the sky still looks black but where the sun is setting the sun behind 

Before Darcy's spell and before Tecna's X-Ray Vision spell which is below

Do you see how grey the blue Sky gets in Tecna's Window of Vision?

An x-ray is always seen in grayscale by everyone that is why our white bones and problems within them stand out.

Tecna's not using an extra super charged version of this but it is enough to convince me why they named it the way they did anyways Skylights? An the X is one another reference back to Bloom's reference of adding X onto their team name of Winx. It is fitting that Tecna gets the X Factor Spell because she and her powers are Xtra Special and Very Unique period. And the show didn't appreciate this enough in the original first 3 seasons, Skylights.

So Plot Hole here has to do with the number of Awful spells Tecna has to use for Sirenix like she has 5 good ones, Digital Strike is really good, Techno Punch & Techno Kick make sense & Logic Net and Digital Net make sense too. The other ones don't make sense Genesis Blow, Biorhymtic Flow (I really consider this one a separate spell altogether.) Neon Splice where the heck that name comes from I understand Neon but why is it a splice it is a full circle with a full doughnut hole in the movie? While I do like the Virtual Projection Shield since the Oil delete spell she has from Believix isn't used it feels very out of place here. And the worst spell of all in Season 5 is her Sirenix special power is "Aura of Sirenix!" this doesn't not fit Tecna in any which way at all, period and doesn't look right it is way too white when combined with Tecna's electricity powers she absorbed from the Jellyfish tells me Aura of Sirenix has nothing to do with Technology.

A better name would have been Electric Pulse of Sirenix or Shock of Sirenix or Stun of Sirenix for Tecna's special Sirenix Spell. Tecna deserved so many better named spells in her Sirenix transformation form.

Pyrix_Fairy even Butterflix powers aren't as stupid as this Sirenix special spell name flop for Tecna.
