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

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?

Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Yellow blemishes1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?
