Upward curling of leaves
One of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Harvesting a struggling plant or just letting it fight
Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

General health
Advice please just on wether it's looking healthy. :) I've been too careful with watering and some leaves turned yellow. Feeding 1 litre every other day but maybe that's too little? Stopped with the Biobiz fish and switch to growbloom. Leaves at the top look droopy still?

Yellowing and dry/brittle leaves
Hello all, I've noticed the leaves are starting to yellow and some are getting quite dry/brittle. Is this a sign of overwatering or perhaps nitrogen deficiency? It is on the same watering schedule as my other plant which looks healthy but obviously has different genetics.

I’m seeing brown on the lower leaves. They also appear particularly shiny like a magnolia leaf. Is this too much iron or magnesium?

Yellow leafs purple stem (not genetics)
Three of the older leafs are turning yellow with purple/brown stains in them, also their stems turned purple with no other stems being purple in the plant. Is this phosphorus deficiency or nitrogen deficiency? Already top dressed with worm castings and bat guano high on P and k.

Magnesium nutrient lock out, triggered by too much potassium ?
@Burmese Thank you so much for your help. 🙏😊 I think it was a magnesium nutrient lock out, triggered by too much potassium. I sprayed some water with Epsom salt on the leaves and it looks like it is getting better. 👍😉

¿planta bloqueada?
Planta amarilla. Medición de escorrentía en 4.1 E.C (muy alta) No puedo hacer un lavado de raices con el triple de agua porque no puedo sacar el scrog. ¿el amarillamiento de la planta se debe a la EC elevada o a una quema por exceso en potencia lumínica ? Flower 42 de 75 días

Lower leaves too pale or yellowing?
I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant. Is this a nutrient/light/watering/lst stress problem if at all? First Grow. Started balcony, moved to tent D23. SF-1000 light, 100% at ~ 55cm from canopy.

Yellow leaves?
This is my first time growing. I have four plants going, this one started a week later and is growing faster but is starting to develop yellow leaves. Not sure why? It’s getting plenty of sun and give it water regularly. Suggestions?

Yellowing leaves, why?
Her leaves started to yellow, probably because she was dried out for one day, so I watered her properly with 1.5l with 5ml of biocanna flores(first time). After 3days I would expect her to be dry again, but the soil is still quite moist. Why is she drinking a bit less?
