Why the yellow?
HazeNKushstarted grow question 2 years ago
Why are the top leaves of the back middle plant yellowing? I did increase the lights for a day to 100% and the plants were not happy. And she got overwatered this week. Could this be the reason? The runoff numbers all seem correct.

Leaves going yellow during flower is pretty normal in the mid-late weeks of flower. As long as you're running the right parameters for your environment and your buds are lookin' good then I wouldn't worry much. If it looks like it's reaching your sugar leaves and they start turning yellow and drying up too then it becomes a larger issue that can be remedied with nitrogen supplementation during feeding.

From The first picture them buds are nearly ready by the look of it so nothing to worry about there as the leaves will start dieing off

Its hard to tell with just the picture, If the yellowing is more striped( intervenial chlorosis ) with green and yellow then it could be
Manganese deficiency. - Add some cal-mag and it should clear up in a week.
Excess Phosphorous/Potassium - new growth will grow thin blades, leaf tips and margins look burnt signs of cal-mag deficiencies show up. lower leaves curl and develop spots.
Good luck and Happy Growing

Living soil and rain water problemHas using rain water killed my living soil?
Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients.
So basically is my living soil now just soil or is the microbial life still there?

What can I do? Leafs starting to turn yellow. First growerYesterday, I noticed some leafs starting to turn yellow and also the tips of the top leafs to be a bit brown. So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?

Nitrogen deficiency but why?My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.

Yellow lower leavesHello,
This is my first grow and now I'm confronted with the first problem.
The lower leaves on my plants are turning bright and yellow. A few leaves have very small brown spots. Can someone help me and perhaps have an idea as to how I should proceed? Thanks.
