You have a ph in your substrate is off. You are in lock out on several nutritional needs. Run enough of correct ph water through soil till run off reads in range then replenish nutrition.

Spots and yellowing on the leaves
Good evening I have an autoflowering at the eighth week and recently yellowing has begun to appear on the leaves that I don't understand if it is the leaves that go towards the natural end or a problem of burning of fertilizer or even a fungal infection.

Lack of water or its something else.
Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄

One of my plants fans are yellowing, spotting, pretty badly. The medium PH is 6.5, same as my other plants, but she just doesn’t seem to be liking it. I’m using nutrients, but not heavily. About a quarter teaspoon per gallon of the flora trio. It’s the mid fans not bottom or new.

What is this leaf showing?
Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.

Heavy fast yellowing
I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?
