Looks like Heat and overwatering + calcium deficiency possibly caused by Potassium excess.

Leaves turning yellow from the bottom up
My older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx Its only on 4 leaves rn

My gorilla girl xl aut is getting a nitrogen deficiency. I think? Im using megacrop. about a ½teaspoon every watering. Also a 1/16tsp of bud explosion and sweet candy. Should I add more? I have the whole line of fox farm nutrients. Anything from there that would help?

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?
I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

Wilting leaves and copper spots? Save Me!
These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

Nutrient imbalance or healthy development?
Are the colors of the leaves a sign of healthy development in the flowering stage, or a sign of nutrient deficiency/excess? After struggling a lot with the nutrition of this plant, I am not sure anymore whether I'm doing it right. Some of the leaves become yellow and fall off.
