Ap0_DrXstarted grow question 2 years ago
I have this symptom, a pattern of rust spots happening on new leaves, I have checked medium PH, which is around 7.5. I think it is Boron Deficiency caused by The medium PH not being approximately 6.5.
I need more suggestions, What do you guys think?

Honestly just fix the ph first. The problem may sort itself out rather easily. I would not add anything until after the ph is corrected depending on your grow media. The optimal ph for cannabis is 5.5-6.5, the lower end geared towards hydroponics and the higher end towards soil.

You say the answer yourself , but still searching for other answers ....
Stupid.
Right Ph is essential tor plant to uptake all nutritions.
For soil its 6.3-6.4

Brown Red Round Spots on 4-5 Fanleaves / fungus ?Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be?
I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.

Tache cuivrés sur feuille.Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda.
Je vous remercie 🙏🌱

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Did I give it too many nutrients? Did I overwatater?
