Could well be a potassium deficiency appearing or some lightburn as it is quite even and uniform.

PH Fluctuation Early Signs?I am worried that I either have early signs of PH fluctuations outside of 6.0-7.0 range or early signs of a calcium deficiency.
As you can hopefully see in the picture the tips of the first set of true leave seem to have little spots of discolouration.
Any help is appreciated😊

Leaves color changing in flower!!!!what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower?
max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout?

IMPORTANT excess/deficiency? What's happening? Flowering is in dangerWhat's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

Dried Leaves, Lockout or Stress. Week 5 of FlowerPlants suddenly wilting & looking crispy like they're dry, but pots are HEAVY! Suspecting root suffocation/rot ("wet feet"). Hard soil crust might be blocking oxygen. Roots are drowning & can't drink. It just happened yesterday since they look dried. Temp is 25C and Air 50%
