Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

lower leaves yellowing in 3 days?
Over the past 3 days my 2nd plant lower leaves started to yellow. Both are fed the same amount and the same rates. I noticed the one that is yellowing the leaves are upwards and that is a good sign, but the lower leaves are yellowing too fast. I am unsure what could cause this.

Deficiencies at Day 60 or natural, expected fade?
Does my girl look like she is suffering from a deficiency or is it a normal fade for day 60 since sprouting? What can I do as she definitely has a while to finish I feel? Any estimates on how much longer she has before getting close to chop? See most recent comment for details.

the leaf yellow
I have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.

The tips of the leaves turn yellow
The tips of the leaves turn yellow. I don't know how to identify the problem, is it the mycorrhizae that make them hungrier? Or do they just have too many nutrients?

Yellowing leaves help please (newbie)
Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

Yellowing some leaves
One of my plants(Quick one RQS) is yellowing some fan leaves. Is she just killing of them because she doesn't need them anymore or Is It some deficiency? The plants look very healthy.

What's up with the yellowing leaves? They seem to yellow from the outside inwards and the tips also seem burnt too. Is it nutrient burn? Excess or Deficiency? It's mostly on the bottom but its affecting some of the bigger leaves in the middle too, Watch the video for an overview!

Carences ?
Les veines des feuilles des Txerri Bilbo Haze deviennent légèrement bleues, est-ce une carence de phosphore ? Les feuilles de la Master Kush s'éclaircissent sur les bords, est-ce bien un manque d'oligo-éléments ?
