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 👌🏻

Overfed P and KUnfortunately i have overfed PK as thought the bottle said 7ml per L but instead was 0.7ml. Noticed tips of leaves the next day browning so checked the feed chart again and pretty much shit myself. Flushed all 3 plants for about 5 mins and now they seem ok hopefully.Week 8

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?Leaves. Color - Yellow

Pest attack. What can I use to eradicate?3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil?
- The temperatures were very high here, exceeding 30°C, this week it will decrease.
- I have other plants to harvest and I'm going to take advantage and clean the grow.

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...Leaves. Color - Dark-brown
