Is this normal?
Hi fellow gromies, my girl is coming into week ten, everything looks great buds fattening etc. But one leaf has drastically changed colour, I know this happens towards end of flowering. But its just the one so far is this ok? Or should I be worried?

On the 31st day I noticed that, in both the plants, the leaves started yellowing from the bottom of the plant! For now the yellowing reached the first couple of fan leaves. You can see that in last three photos. Could be some pH issue or some over/under feeding?

Lower leaves yellowing and curling down
Do anyone know what's wrong ? I was thinking they were getting to much light in the tent with my flowering autos... I'm quite sure it's not about watering

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?

Tips turning into yellow
We started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)

Nitrogen deficiency or could it be nothing
In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.
