Can you spot the problem? (pics)

No variable has changed in grow tent.

Only thing i can think, I sprayed tent with bleach solution before i went to bed then next morning...

Probably the bleach

^ more than likely, bleach makes a chlorine fog as it evaporates, mist them with some fresh water till they're dripping to wash any remaining residue off, then just let them recover. and take the plants out of the tent if you do any more cleaning

Thank you
