It looks hungry man, like a N deficiency judging at the yellow and extra crispy leafs at the bottom. Suggest upping your dosages if you arent using 50-100% of the recommended

Or with biobizz feed at 50% strength every feed all the way through, no need to water to much runoff either

Seedling leaves are discolored and starting to curl
Not sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!

Seedling yellow leaves
Two weeks ago I started these 3 seeds, all of them are in the same soil but two of them have yellow leaves. Maybe someone can tell me why. I think it is not normal in this young age. Please look at the pictures to compare the three plants. Thanks for your help!

Yellow lower leaves on 8-9 week old plants - Deficiency or age of plant?
Lower leaves are starting to yellow on some of the plants. I think I have corrected my cal/mag issues but now these yellow leaves. Going into week 9 of flower. Is this normal because of the age of the mature plant or a deficiency? Or is it still cal/mag deficiency?

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Excess or Defiancy?
Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.
