You do not have a diary so we are guessing based on one photo. It could be a magnesium deficiency.

Did I do the right thing? Pls check my update on this week!
Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Purple leaves getting worse!?
So I started getting light purple/yellowing last week, after my last grow question, I landed on potassium deficiency. I gave a healthy dose (2 tbsp in a half gallon of spring water) of Fox farms big bloom (0-.05-.07), within the last 48 hrs and the purple looks worse? Any ideas?

Over watering? Asked a similar question before but want to save this plant
This has gotta be overwatering, right? The soil + pots I'm using don't seem to drain very well. Started drooping like this when I added a humidifier at around 70% relative humidity. Maybe pushed it over the edge? Going to home depot. Perlite? Change out the soil? Better pots?

End of Cicle or High stress???
Good morning everyone! First, thanks for the replies to my last question. 2 of my 3 girls are doing much better, but sadly one is still very stressed. As a beginner, I’m not sure if it’s normal end-of-cycle or if she’s still suffering. Thanks, Jack
