HELP PLESSE!Yellow leaves during flower!

I’m on day 63 of my Autoflower Lemon Haze. She is almost finished and most of the fan leaves on the entire plant seem to be turning very very yellow. What is happening??? I’m so close to cutting her down and don’t want to ruin her in these last couple of weeks.

Support ticket? And normal lighting.

Am no expert, don’t take my advise at all, just going to say, I think she is at the end of her life cycle… I think you’re almost time to harvest. I see good amounts of amber…got a jeweler loupe?


I don’t have a support ticket. I’d be happy to fill one out. Where could I find this ? And I’m using all LED. Spiderfarmer and HLG. Light cycle is 19-5 since they are autoflower.

Seed bank stated about 75 days for total grow so only about 2 weeks give or take left.

I ordered my jewelers loupe as well as a very strong magnifying glass and a macro camera lens. But everything is delayed to the damn virus. Should be here next week so I’ve been doing what I can with my phone.

How old are plants.

What are you using to measure PH and TDS and when last calibrated?

63 days of a suggested 75 day grow by the seed bank. And yes they were brand new this grow.

This is a picture of the yellowing leaves I’m concerned with. It’s only the fan leaves but over 50% seem to be turning yellow.


Do you have a runoff TDS? Plants still have a ways to go and you will have to ride out the yellowing leaves (they won’t recover). At this point I’d like to see a runoff below 1,200 ppm or so and supplements going in around 700 ppm. Flowering nutes usually are shy nitrogen so the yellowing.
