Why the yellow?
HazeNKushstarted grow question 3y 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

Nutrient Lockout or Nitrogen deficiency (i.e need more nutes) or Fungus (see stems)My leaves are yellow but some are turning green. Do they need more nutrients or lockout? I have not gone above 1EC but have seen both strains handling 1.5EC+ in other diaries. All three plants are drinking the water in trays.

Yellow leaves at the end of flowering, should I worry?I can use some help on this one. I am pretty new. The variety is called Hawaiian Staycation. It has done well and we are in the last week or so of flowering. It got a bit dry in the tent and the leaves really yellowed. I plan on harvesting next week, should I be concerned?

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering?

Nitrogen toxicity or deficiency? Or just PH issue?Hi buds.
Gonna need your expertisè again. My Grandaddy Purple auto is showing signs of something.
Leaf claw: N-toxicity or PH issue
Leaves fading: N-deficiency or PH issue
What do you think changed this one leaf, and what do you think is going on with the other leaves?
