Calcium deficiency
blackrainstarted grow question 5 years ago
I already had a question a week ago, now it's easier to see, camera still bad.
But here are some fan leaves which I believe are showing a calcium deficiency.
Calmag is in the post, just waiting for it.
Is it for sure a calcium deficiency only? Thoughts?

Rust spots on leaf edges and veins, Slowed growth, new twisted leaves, brittle stem. If you have one or more of these symptoms you likely have calcium def. Analyze root PH first and foremost and correct if necessary. An acidic soil with PH at or below 6.2 can easily develop cal def. Aim for 6.5-6.8. If PH is good then proceed with calcium supplement as per directions. Too much Potassium
Can also trigger a cal. def. Cheers 🍻

For sure you can fix by giving calmag product, but it will not build your organic soil. Can also top dress with garden lime at a rate of 1 tsp -1 tbsp per gallon to balance your PH and provide calcium all at once. Cheers 🍻

@Cabbagepatch , my waterings have been between 6.1-6.3ph, I got calmag in the post, I do have ph up/down but I've read just to let the soil do it's thing, especially since it's organic.
Think I should just add calmag with it's next feeding as soon as it comes, I've gave it a regular watering since.

I did lower the plant (was way too high) so may beight burn - but it’s only on some plants

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

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 🙏🌱

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.

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!
