one old leaf at the bottom? If isolated, i'd ignore it.. a plant does shed a leaf on occasion.

It looks like one of the older leaves which happens, but also looks like it’s had some liquid spilled on it at some point as well. Not much to worry about at the moment. The others seem fine

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.
Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?

Normal Yellowing?
Is this leaf yellowing normal for mid flower? I’ve been feeding her Greenleaf Nutrients MegaCrop, Sweet Candy and Bud Explosion with some GH calmag.

Yellowing Leaves with Purple Spots – Need Help
About 2 weeks ago I posted about my plant's leaves turning yellow, possibly due to a grow light I'd just moved closer. I repositioned it to ~30cm, but things have worsened over the weeks: many leaves are discoloring, especially near the top, and some show purple spots. Any ideas?

Yellowing plants
Based off week 2 day 7, does this look like an over watering issue or something else? This was the first watering where I soaked their containers. While they were in solo cups I tried to keep watering volume low.

Possible toxicity or deficiency?
I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?
