Can't find cause of my problems in any other pictures. HELP pls!!!

Oh no! It's happening again!!! Think there may be a good clue here that points to lights though? I've circled the leaves in my picture from 4 days ago that were looking much improved. Then a picture of where they are now. There was a leaf across the one that has turned red, that has 'shaded' the one underneath and prevented the same discoloration. What do you masters reckon?

[seabadger]

oh, these were all shot in 'nighttime' on camera flash. Going to see if there's a ph test I can get on amazon....or is that a grow shop specialty?

You can get them on amazon pretty cheap I think like 10$ or there abouts cheapest one is in the pool section it’s like 5$ but that’s the strips and I don’t like them..

the curling twisting leaf could be bugs, could be many other issues, have you inspected the under side of the leaf with at least a 30x lens?
My thing with amazon is the same as walmart, I can beat their prices!

IMHO based on the curling leafs I would guess overwatering or wind burn...
