The light markings between leaves is magnesium and spots are calcium sign. Also showing potassium deficiency. So I am perry sure your ph had drifted upwards too high in that one.

Cal mag. Your ph is likely too high in this one due to coco amount used in substrate. So your experiencing a lock out.

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

I’ve got a little greenhouse grow (I think this is a seedsman lemon auto), but haven’t been able to give the plants as much love as I would have liked this year. I’m a bit worried about this one, any advice would be greatly appreciated if anything could be salvaged?! Thanks

Little seedling having a hard timr
So guys; I'm worried about this seedling. She's having trouble on keeping up with her sisters. I noticed a yelow color on their tinny tips 🤔 Cotiledons got brown pretty quickly too. She took longer to "open" the cotiledons after popping from the soil. Should I do something?? 🙏

Bottom fan leaves turning Yellow on week 8... Emergency, or all good ?
I know It's a Nitrogen deficiency. No nuts during veg (and fine!), and she's having flowering nuts since 2 days. I know it's normal at the end of the flowering, but i'm wondering if that's too soon !? Not sure how many time left before harvest!? Big problem or not?

Why are leaves yellow?
As shown in the photos, I find yellow leaves of Northern Lights Auto. Until yesterday she has been growing in good health, but now her leaves look drooping and some of them yellow. Also she does not drink water. Why do you think it is? (deficit of nutrients?)

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....
So, I have 3 plants: - 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light. ?? The left plant is showing a few defects. Anyone?

¿Qué le ocurre? ¿Tiene recuperación?
Las California Kush no acaban de recuperarse. He regulado el pH y la EC de todas las plantas. Una parece que se recupera y está echando hojitas pequeñas de un color sano, pero a la otra le salen muchas manchas en las hojas nuevas.

What is happening? Leaves

Is this nitrogen deficiency or something else?
Hello everyone! One of my plants has some fan leaves and new leaves yellowing at the bottom (and some are crispy). The plant is very bushy but from what I understand this could be nitrogen deficiency but wanted to check. The other plant is smaller and doesn't have yellow leaves

I may have over watered or it could be nutrient lockout. I only feed them every 10days to 2wks. I was switching them over from 1 fert to bloom fert by mixing 1 tsp of ea into 1 gal water but I did it 2x in a row. BEST WAY TO FIX THIS ???
