What's she trying to tell me?

[Lady Lollipops]

I've lowered her temp to between 73 to 77. She seems much happier.
She's in Coco loco. I've only given her tap water (set out 36 hrs.)
I'm checking weight of sack (3 gal) before watering. Watering from outside toward her at root base. I'm using a one quart Mason jar not quite full for watering. Humidity is about 48 to 55 ‰. We just turned on Ac in house so I'm keeping track of it closely.

Leaves have some mottling. The tips have lighter spots. Lowest leaves are paper thin and the tips closest to the stem are curled up and brown.

She's trying to tell me what's wrong but I'm not sure.
Thank you!

Are you checking ph? I check mine religiously

How much are you watering? At that phase I water very little. Also are you using tap water or RO water?

Also you may want it in a little warmer spot in the beginning.... I noticed the same thing with one of mine, closed the door to my closet it’s in for a few days to let it sit around 80 degrees.

Tap after sitting out 36 hrs and Ph checked. 3 gal grow sack. Watered once with just under a quart working from outside toward stem base.
No added nutes.
She drops pretty heavy if temp is over 78. She really seems happiest at 75. Maybe the strain? Gelato by fast buds.
I "think" she was too hot and dry.. I think she also might be over watered. I would say under watered but plants droop more than she did if under. But I weighed my sack.. .. Also giggling at weighing my sack.

You might try cutting a milk jug in half, the top half stick over the plant like a dome. She def looks over watered to me. But I’m no expert.

Also I keep my water between 5.5 and 6.5.

Thanks! I'll give her a bit to dry out.
