I cant tell what's wrong with her. I recently upped my CalMag nutrients cause I originally thought this was a Calcium deficiency (full nutrient breakdown in diary). I dont want to hinder my harvest so any insight?

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?

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

Yellow spot on my leaf. :) PH fluctuation ?
(Water change) I had set to 5.5 PH and waited 20 minutes. I put in my fertilizers, everything was fine. The next morning the ph had dropped to 4.7.. So I put it back up. The next morning yellow spots appeared on the leaves. Did you confirm that is due to ph fluctuation ? Thank's

All newborn leaves are turning too much yellow
All newborn leaves are too much yellow. Do you have any idea what problem could be? 7-10 days ago turned to 12/12 for bloom phase. I think its light burn, BUT even lower newborn leaves are yellow.
