At this point I would not worry, plant is almost done, so it's natural for the foliage to start to die

This girl is the only one in the growth tent (she is with other 3 strawberry cheesecake auto plants) with leaves curling up. The lamp to plant distance it´s at 80 cm, and the wind source its not hitting her directly. Could be overirrigation?

Help calcium deficiency
I think I have a bad case of calcium deficiency? This started shortly after switched to 12/12. I added 1/4 tsp to a liter of water 2 days ago. I’m not seeing improvement. Am I right ? Will the leaves turn back green (how long)? Is it something else? Will it die?

Underwatering Issue or something else?
I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering? I’ve been pHing between 6.2-6.4

Discolouration progressing
The first pic is from 2 days ago, now the yellow has turned to brown spots and is beginning to spread to others. I'm hoping it's an easily corrected nutrient imbalance, please help

1st plant. Seems stunned and yellowish with black dots tips. Can anyone give a hint?
Hey, guys! How are you doing? This is my first plant. It is 4weeks old, planted on cocó-perlite mix. I find it growing too slow based on other diaries, and it is starting to show these yellow with black dots tips. Anyone can tell me what’s going on?

Any ideas to what might be causing these leaves to yellow/die? Only reasons I can think of are nutrient lockout, having the lights too close (although I've heard with CFLs theres pretty much no such thing as too close) or possible having the heater running, or constant fan air
