answered grow question 6y ago
From the looks of it, it looks like a leaf dying from not getting enough light which is completely normal. Hopefully, I answered your question and remember " Happy Growing".

Yellowing 1st set of leaves
Hello, I'm on Day 11 from seed in Coco/perlite using dry Amendments. My girls are yellowing from centre out and have been stuned a few days now. I'm under the assumption it's over-watering. I've air rated, dropped humidity to 45-50%RH. Am I on the right path?

Only Fan leaves starting to turn yellow?
Why are only the Fan leaves starting to turn yellow from the outside inward? All other leaves are okay and green. Blueberry Auto 10 weeks old, organic soil grow. Should I remove? Comming up on the flushing period soon.

Lack of water or its something else.
Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?

Is this magnesium deficiency?
After some googling, it seems to match? But the yellowing on mine seems to be very concentrated just on the tips.

Potassium deficiency?
Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

bottom leaves yellow
Helloo So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening
