Second grow problems?

Hey, I'm almost 4 weeks into flowering in my second grow, started flower Dec 15th.

I'm nervous that the plant is starting to show problems.

Information:

Strain strawberry cough
I had 2 plants, now only this one.
The other one didn't grow nearly as big as this, no idea why, and it died, all leaves wilted and it had only small buds so I threw it out..

Light time is 12 am to 12 pm night
Dark time is 12 pm night to 12 am morning.

Light time temperature can be as high as 27 degrees.
Night time temperature can be as low as 16 degrees Celsius, but I'm now doing what I can to keep it at 20 degrees, because I read that the difference to temp. Day/Night must be max 10 degrees Celsius.
Humidity is as high as 70% nights I believe and as low as 20-30% daytime.

Given water every 3-4ish days, is about 2-3 litres. (Approx 2,5 litres. When soil feels and looks dry)

No air intake, but there is an exhaust to drive away smell and to suck heat away from lamps, I keep tent open for this reason, due to vacuum otherwise.

I open windows in my house during daytime as much as I can to refill air in the room.

Please tell me, is my baby dying?!?!?!? :(((((
:( :(

Like mike said what medium are you using what and how much are you feeding them. If it’s coco what’s the ph of the water, what are you using for water tap, well , glacier runoff. I like to keep my rooms 73 day and night the one that died the low starting temps are no good. If your in a tent and exhausting out open one of the flaps to pull air in all the time those little guys( girls ) to a good fresh air exchange. Having a vacuum as you put it or negative pressure is good. No leaky smells and a good turn over for the air in your tent.

Regular potting spil I bought at a flower shop, mixed in around 30% perlite.
Water comes from my tap water, which I let be for 2 days for chlorine to evaporate.
I ph water to 6.5 once chlorine has evaporated.
I'm sorry but how is negative pressure good? The tent will just contain no air or co2 for the plants then? I might have read what u said wrong though.
I understand that exhaust is good even without intake, but I read I should keep my tent open for the air to be able to be sucked in, not closing the tent which will make vacuum because exhaust takes out all the air and co2 of the tent, hence why vacuum is bad, no?

fix humidity swings, ensure there are no light leaks and give it a general feeding, I dont see anywhere youve fertilized or anything? top dress anything? what kind of light?

Having the walls suck in a little in the tent isnt sucking all the air out, it is slightly dropping the pressure in the tent relative to the outside, air will leak in through the fabric and zippers and such. It's like a weather front moving through the area the pressure drop is measurable but does not affect the concentration of gasses present, just ever so slightly the mass of those gasses is impacted but not to any appreciable level.

No it doesn’t deplete anything do that it’s actually replacing and turning over the air an all the gasses in the tent. It’s a good thing all my rooms have such a negative pressure they’ll shut the doors with ease. Plus with a negative pressure grow area none of the smell will have a chance to go anywhere except Thur the filter another good thing. Are you feeding them anything? Does that soil have nutrients in it ? Also does your fan stay on 24/7 because it should especially at night when the humidity raises it shuttle it out honestly she looks super hungry and more than likely depleted the soil already.

How can I fix humidity swings?
Viparspectra 600w there are 3 of them.
I used ferts but only a little since I'm not really sure how to use it, so I just give it a little once a week ^^ maybe I should give more?
Are you sure about the negative pressure? Cause the tent really looks weird when I have it running, it goes all inwards and such because of the vacuum.

There is perlite in the soil, but not much, 30% I'd say, but none at the very top layer.

Not homemade, but thanks :)
It was bought on a website, can't remember which.

I gave ferts 3 or 4 days ago but not much, also 2 weeks ago, but not much I believe.
Maybe I should add more? Or? :p
Canna flora is the ferts I use.

I am absolutely sure on the negative pressure.
You need to follow cannas feed schedule those girls will die out if they're not fed. They are definitely in need of food that's why the leaves look like they do. For reference man I run three rooms all together totalling over 6000 watts anymore and never run into issues.
