If it's not getting any light, that could explain it and it that case, you can snip it. Otherwise, check your pH, make sure you're not overfeeding, and use calmag if you're not already. If it's just one leaf, don't do anything drastic unless it starts spreading. Cheers friend!

If the yellowing is on the whole leaf, then it is nitrogen deficiency, if it's hapenning in the tips and edges, then it's potassium defficiency. The first case needs growth nutes, the second case needs flower nutes

Heya!
She looks a little hungry. Up the feeding next water and watch to make sure symptoms don’t spread.
As usual, make sure the pH is in check as well.
Cheers!

Leave's tips color turning yellowCiao a tutti, da 2 giorni ho notato che le punte delle foglie si stanno ingiallendo. Ho pensato di allontanare la luce dalle ragazze, nonostante stia usando una LED (marshydro ts1000). Sapreste dirmi cosa sbaglio? Dovrei agire anche sulla quantità di nutrienti?

Nutrient imbalance or healthy development?Are the colors of the leaves a sign of healthy development in the flowering stage, or a sign of nutrient deficiency/excess? After struggling a lot with the nutrition of this plant, I am not sure anymore whether I'm doing it right. Some of the leaves become yellow and fall off.

Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency?
Or is it still cal/mag deficiency?

Nutrient burn, magnesium def, light burn? Leaf tip yellowing but not turning brown/curling4 week since planted autoflower, both started getting this at the same time. First time running autos, grown in FF Happy Frog soil. Soil was used for 3 weeks in a different grow so nutrients may be needed. Light burn, mag deficiency?

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!
