Yup the other growers are correct seems to be too much water thats why the leaves arre drooping down like that and the light colouring and where it is is most probably the start of some kind of toxcity I would put my money on too much nitrogen. Wait for her to dry out then feed with ph balanced water again wait for her to dry out and then continue feeding according to your feed table she will take time to recover but she will be okay :) Advice on watering only really saturate the whole pot if your in the later stages of flower usually they cant uptake that much and measuring run off is not more important than your plants health :) Best of luck 👊
Looks like she is over watered. You want to let the medium completely dry out before watering.Its hard to say if the marks are related with just leaf pictures How does the new growth look and where on the plant are these pictures. Could be from a ph imbalance in your medium.
