I think it's just a bit of root stress not really a nutrient issue, it's fairly normal towards the end of a hydro grow, from what I can make out so far it's nothing to worry about.

No diary = no information = can't help! We know nothing about your grow, just a picture of a leaf. Put together a diary and then ask your question!

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.Week 6

Friends need your help! the leaves turn yellow at the seedling stage!Friends, help me figure it out!
First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom
now I'll tell you how it was!
after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm
the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0
drip irrigation works constantly!
The temperature in the box is 23-25 C - humidity is 40-60%
Inside, there is a fan on top that turns 360 degrees to blow the plants!Leaves. Color - Yellow
