Im just really trying to make sure i do everything right. I have had less than desirable quality/quantity product in the past. I am hoping this is my first crop i can be proud of.

As a precaution i did just do a sort of halfassed flush on the one with burned tips They are in 5 gallon fabric pots. I gave it 2.5 gallons of Phd water and lowered my fan closer to the pot to help dry it out. I guess i will monitor it and flush more if the burn spreads.

My temps i think may be a bit too low too but there's not alot i can do about it.

This is 3 weeks since the day i flipped to 12/12

They look pretty good. But like you mentioned the temp might need to come up a bit.
If they were mine I would first get the fabric pots off of the floor. Then check the root zone temperature. And if you can get a heater and a thermostat controller, do it. Try and keep your tent around 80f lights on and 75f lights off. Inkbird has environmental controllers that handle heat and humidity for about $70 u.s.
Purple/red petioles lead me to believe your roots are running a little cold. Cold roots have trouble using potassium and phosphorus and will first show those symptoms in the petiole. Shoot for the mid seventies Fahrenheit in the root zone. Your plants will thank you for it and reward you with a much better harvest.
Good luck friend!

Yeah my temps are usually mid seventies during the day but fall to the 60s at night. Humidty usually between 35 and 45%

Any heaters you guys can reccomend For a 2x4 tent?

You can start by either insulating the floor under the tent, or in, up to you.
Use something to raise your pots as stated, pot with a cake rack, anything non porous and will sit over a liquid collection item ie deep saucer.
Whichever heater you choose, make sure it will restart using same settings in case of power failure, unplugging, etc.
Good luck.

So i appreciate the advice on the heater. After doing some thinking i may have to just try to insulate better.

My grow tent is in a space with no outlets and is powered via extension cords. I already get anxiety about running 3 lights, and 2 fans on it.

I am not sure at what point overuse of extension cords becomes a fire hazard but I think that out of an abundance of caution i will not use a heater.

I did order a window covering and am going to do my best protect it from getting too cold by blocking drafts and whatnot.

Extension cords are fine...I run some.
Just ensure the Guage is heavy..12 or less, and as short as the requirements allow.
Run the heater on its own cord.
Peace.

Yeah a big fat cord. And try to keep it as straightened out as possible. Coiling extension cords for heaters or ac creates a resistance coil that can lead to their failure due to heat, that can lead to fire.

I was also having doubts about high watt heaters in a small tent which is why I went with a small 200 watt heater. The average size ones sold on Amazon and elsewhere are all 800-1400 watt. You might wanna check your amps see if you can even handle that.

Honestly, I am just not gunna risk it.

The temp swings are still within what the plant can survive. I have window insulation on the way, and that will definitely help with the temp drop at night. The tent is in a closet with a window and that window is quite drafty.

Daytime temps are usually upper 70s sometimes up to 80 or 81. The temp last night in the tent fell to 58 though. At least spring is coming and temps won't be this cold for too much longer.

Also on the brightside i have read that low temps can cause more purple buds (depending on genetics of course).
