Nute deficiency or burn??
Steamedclamsstarted grow question 4 years ago
Deficiency or nute burn. Plant is otherwise healthy. Day 37. Only had two small feedings which were at the 50% rate of seedling dose. Soil is a cutting and seed mix with added nutes. The black marks are only on this one leaf which is new growth on the main cola.

Looks like a sulphur toxicity but I’m fairly new to growing so definitely get a second and third opinion when diagnosing, good luck 👌🏻

Calcium deficiency?I recently bought Calimagic for my calcium fix. Prior to this week I have been using tap water for calcium. Is 2mL/gallon of calimagic too little? Noticed some leaf damage I believe to be calcium deficiency.
Does she need more calmag?
Thanks for your help all!

Leaves looking f’d?What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Foglie bruciate.Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.

Plant HealthI have a few brown spots and slight yellowing on a couple of my 3 finger leaves and even some on a 5 finger (#2). It seems to be getting worse every day. I have done a lot of research to find out what it could be but am very confused. Any ideas? Pictures from 2 different days.

Black marks on leaves of a slow grower.Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

Brown spots/yellow tips after accidentally breaking a bladeHi!
I accidentally broke an older blade from one of her leaves, and after a couple of days that leaf started getting brownish spots and slightly yellowing tips.
Is this normal to happen after a broken blade and will eventually die off? Or is this any sort of deficiency?
Thanks !
