Hi! This is my 7th? grow, and a week or so ago, one of my plants started showing signs of distress. Now it has progressed into the following picture, and a few other plants are showing early signs of the same distress.

I am using a heavy-fertilized soil, and during veg the leaves were very dark, and I didn't start using nutrients until 2 weeks before flower - and I am also using lower amounts of nutes that what is recommended on the bottles. (due to the highly fertile soil).

I am not sure if this is happening due to deficiency or toxicity - would love any input.
Besides this the plants look super healthy. They have become a little more light-green the last few weeks, making me consider if they are slightly malnourished.
Using the advanced nutrients complete lineup (grand master lineup) - with about 1.5ml/l of the base nutrients feeding once a week. (1 of 3 waterings per week)

Looks like a ph issue or toxicity problem which can be closely related

But your spots. Looks like a spray or a splash of nutrient rich water. Then the light fried the liquid spot. But others with more level of knowledge will chime soon
