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

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

When to start using Cal Mag?Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?

Yellow lower leavesLower leaves are turning yellow. She just started her second week in flower.
My first thought is I'm not feeding enough. She is short, but still a lot of plant here. Here upper leaves are a nice shade of green. She prays all day long.
Is this a problem.

Is she too far gone or can she come back?Week 8. Biobizz Light Mix, Biobizz Grow, Biobizz Bloom and Top Max (1ml/L up to 2ml/L). Ph 6.2-6.5. Leaves started yellowing just over a week ago so I started to feed with CalMag at 0.6ml/L. Some of the top leaves are starting to die and new growth is turning yellow quickly.

Spots on leaves and little twisted...Spots started slowly showing when it had a different 600w light, too much heat back then, this started a little "save operation" changed light, made the plants look a bit healthier but now it looks like the spots have spread and also affected the leaves above... Are they healthy?
