Leaves of young plant are becoming yellow
The leaves of my four week old Stress Killer are becoming yellow from the outside to the inside. I am a total beginner and I read that this may be overwatering, underwatering, overfeeding, underfeeding, so I am confused.

Seedling leaf color is very light green.
I'm wondering if there is any reason to be concerned with the lighter color leaves of one of my plants? They are significantly more "lime green" than the other two. he one in question is the bottom one in the picture attached. It is clear how much darker in color others are.

Magnesium - Nutrient problem
Do I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly. The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1. Has anyone the same problem? Thanks!

Gelbe Blätter, mit Lila Flecken
Meine Pflanze hatte Nährstoffbrand, dann hab ich erstmal keinen Dünger mehr gegeben. Jetzt bekommt die Pflanze gelbe Blätter mit leicht Lila flecken. Nährstoff mangel? Oder Blattverfärbung durch Blüte? Oder immer noch Überdüngung? Ich verwende BioBizz Starterpack.

Hey guys so my plants are starting to turn this yellowish color and I’m not sure what the problem could be. Sorry for the second pic, it’s kinda blurry but that’s the actual color compared to the other leaves. It’s my first grow and I’m kinda lost on a solution . Many thanks

PH Fluctuations and/or Nutrient Issues?
I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

Droopy leaves, weird spots.
Does anyone know what's wrong with that bottom left plant? Those spots appeared pretty soon after I cleaned those filters. I'm thinking that it's a stress caused by that cleanse, no chemicals or such were used, but some roots were torn in the process. Deficiency? Disease?
