Use Ebson salt like teaspoon to a gallon to get your leafs to curl back down and then you need nitrogen

Upper leaf
Although the general condition of the plant looks good, some upper leaves started to claw. I would like to get expert opinion on the cause and solution of this.

PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)
TS1000 (150W x 2), set to 75% at 12-14". "Photone" app (yes, not as good as a PAR reader) reads 580-700 PPFD, so I sense these girls aren't getting as much light as they could. I've read that pushing 900 PPFD is desired (CO2 bags);fan leaves curled. How should I think about this?

Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok

Deficiency?
Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmk

Is this normal?
It's been awhile since I've had little babies and I don't remember any others doing this. The first two leaves are curled under and it popped out like this.

Leaf Curling - Late Flower
Growers, Small issue. LOADS OF LEAF CURLING. I assumed it was nitrogen so I stopped all nitrogen for 3 weeks & no fix. Flushed with 20L of water thinking its possibly salt? Nope still got a curling problem. Any ideas why this is happening & is it a big issue with 3 weeks left?

Curl up leaves week 2
Help guys! It seems to me that the leaves look a little twisted. What is the problem? May be because it is too hot outside? And also have small white spot on one leaf.

Starting Training
I'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️
