I just don't know lol

Growing indoors, in Soil
Usually water every 5th day with a pH of 6.4 - 6.7. Temps stay between 70-75f and Rh bounces between 38-45.
The plants an Autoflower that broke soil December 9th and stopped stretching and finished crowning around January 28th. About 3 weeks ago I got what I assumed was a calmag deficiency. So I gave her a half strength foliar feeding of "Sensi Calmag Xtra" and then 2 days later (when she needed a watering) another half strength dose watered into the soil. Now she's rolling her tips up, so.. she's really mad about something.. I thought nutrient burn or pH was off in the soil but I haven't fed any bottled nutes (other than the calmag) and a slurry test says pH is 6.58 while run off says around 6.46. I'm kinda lost as to what the issue(s) are/is. Any help is appreciated.

the tips burnt show that she had a bit too much bloom nutrient .. it yellow from the top so it probably locked an immobile nutrient, hard to say which one
what light do you use and how far ?

No nutes given, FFOF and perlite maybe 4 gallons to 1 gallon of perlite.
She outgrew the tent so I pulled her and the light out. Canopy is a SF-1000 (spider farmer LED) not sure what the actual draw is. Also set up a few light bars (LED) on the sides just over 16" from the top most flower.

I'm having the same issue brother

And I think I just figured it out. She stretched and outgrew the tent, so I pulled her out. She's now in a Rh lower than when she was in the tent (50-60 in the tent) now maybe she's pissed it's way lower.? Too much transpiration.?
It can't be that simple can it.??

Indoor soil grow as well, not using nutes either

She looks a little hungry. Like old school skunks acting like they got a tapeworm. lol
