Leaves are yellowing
smoke24answered grow question 5y ago
I'd check soil/runoff ph and make sure you are in the right range. Also try not to have water sitting on the leaves as it can act like a magnifying glass, and burn the hell out of your leaves. Happy growing.

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??5y ago

(Mimosa auto in coco) Yellowing tips on new growthThe top of the plant (new growth) is showing some unhealthy signs.
The tips of the leaves are yellow and there are lighter green stripes on the leaves themselves.
I googled and the signs match to a number of deficiencies, but i lack the experience to diagnose correctly. Plz help3y ago

Losing colors :'(I watered only 2L of water without nutrients this week (pot 30 L)
You can see it on the diary photos, the plans have lost their colors (yellow).
I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion
Thanks !3y ago

Strange leaf shape, who has encountered this and what came out as a result?1. Am I right that it was just overwatering?
2. Who has experienced the same thing?

Organic grow, yellow leaves, autoflowerFirst ever grow. I'm in my 5th week of autoflower, organic grow. Using the bomb paonia soil, raging kush light and boogie brew tea and filter to water. Temps are steady around 86. Started noticing yellowing on bottom leaves. I'm pretty sure it's from under watering? any feedback?Leaves. Color - Yellow

It's been a week since I switched to flowering and new growth on the plant all has a yellow/lime green colour but this seems to go away when the leaves fully grow out and growth in general has not slowed down. Based on the pictures in my diary should I be concerned?Week 6

What happened to this seedling?This seedling out of 5 is the only one not looking good. Everything was the same for all of them, but this one took a turn for the worst. It's ok if it doesn't make it but I do want to know what you all think might have happened to prevent it in the future (or save it now)Week 2
