That is a calcium supplement issue normally. Especially when into flower the plant uses it all up and its stored in the leafs . Just add abit cal/mag to your feeding

Why are my leaves getting brown yellow?
My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.

Brown spots on the Gold Leaf?
Brown spots with light yellowing. Possibly calcium deficiency? This is only happening on the Gold Leaf. Neither of the GDPs are showing these signs. This has happened over the last 2-3 days.

Orange Spot in first set of leaves
If you can see Veg Week 1 Photos, Photo named Day 7 Zoomed, I have been seeing these dots for 2-3 days now. What is it? how can it be solved? FYI - These were the first set of leaves, others look healthy. My guess - nut water got sprinkled or cal/mag deficiency.

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

Handel es sich um Kalzium oder magnesium mangel oder ist das ein Pilz
It's Skywalker from Dutch Passion, now in week 3.5 of flowering. I fertilized it with Green House Feeding Grow at the beginning, and after the time change, I used Bio Bloom according to the manufacturer's instructions. The soil from Plagron has brown spots everywhere for the past 2 days.

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

Stickstoffüberschuss?
I have a problem with my auto that it's hardly growing in height, and there are spots on one leaf. But I have the feeling that the other leaves are also too dark? Maybe it's not growing anymore because of a nitrogen surplus? Should I water it without fertilizer for now?
