It has some spots which I think is calcium deficiency. Its drooping and has dark leaves. What you guys think
Nitrogen toxicity

Too wet and too cold by appearance.

It looks pretty good besides what you mention. Drooping is usually overwatering or a sensitive plant. There is some tip curl from N, and a few Ca spots you highlighted.

Looks overwatered. Overwatering can cause ph to go more acidic. Could be the reason for deficiency?

Or excess nitrogen blocking

Or that.

By why overwatering? I literally waited like 8-9 days for it to dry.

How would you go about fixing this? I gave it a slight flush last watering. I flushed mane 3 gallons through her. I wanted to see if I could get rid of some and not get rid of all tho. Clearly didn't work. Would you guys say to flush throughly, mabe like 10 gallons, then give nutrients? I have fox farm trio, and cal mag. I will have to look at the week, but I think it may week 4 or 5. They are autoflowers. 3 gallon pots. Kingbright 320w light. Did not give any nutes yet. Im using happy frog.

Your dry backs should only take 2-3 days. If it takes longer than that water less until you achieve a 2-3 day dry back interval.

I recommend dosing your nutes less and don't flush anymore. Just keep the ph in check and feed her a lower dosage and observe for a week. She'll bounce back. If you have to wait another 8-9 days for a dry back try placing a small fan near the pots for faster dry backs then try less water between waterings.

Good advice in both comments, OP.

Overwatering causes the roots to stay wet which is exactly what is happening when it takes that long to dry. Elevate the containers whatever they are. Use a skewer or something else long and thin and pierce the hell out of the medium all the way to the bottom. Especially under the plant through the mass of shit and roots that's there. Do this between every feed or watering.

The real culprit I think is the medium itself. Any medium taking that long to dry does not have enough aeration. I would transplant ASAP and use a lot of Perlite in the mix, roughly 50-50 compared to your current mix. That will solve this issue imo.

‘That well might be it …. Long periods of wet periods can be a sign of poor drainage / evaporation / even your grow temps.
She looks soggy ….
Even low lighting for plant can lead to slower water use .

Laying aside any discussion of the wisdom of flushing the medium...
What size bags/pots are you in? A TRUE flush would definitely be more than 3g in something like a 5g bag. It would be more like 10 or more.
I always think a flush is really only needed if you're locked out in the soil. I thought I might be this past week, but on watering day I checked my runoff and it was ~800ppm (1.6EC) on the first water that came through the pots (at about 1.3 gallons in the top). I generally do 2g per 5g bag, so I decided to see what things looked like as I poured more. At 2g I was at ~675ppm. I decided to drop another gallon in each, and that brought my ppm down to ~525ppm (1.5EC), and that's with water that was metering at 330ppm to start.
The reality is that if you're watering to some runoff, it effectively pushes out a lot of the older nutrients. I've been feeding @ 675-725ppm so ending up on the back side of a watering at 2g with 675ppm seems pretty reasonable.
I almost always get some minor spots that look like that calcium deficiency right about 3rd solid week of flower, but I can't decide if it's from the hardness of my water screwing with the P/K uptake, if its because the calcium in my water isn't 'potable' by the plants, or its the plants just shifting to higher P/K needs in flower and not catching that change over in time.
