Hello it seems you have calmag deficience. How do you try to correct it. You can use epsom salt which is the best for this. You can mix it in water and mist your plant for a quicker effect. Good luck. Bye

Flecken auf Blatt und Halm oder Helikopter-Mutter
The 2 spots on the front leaf and the dark areas on the stem are bothering me a bit. Do you think the plant has a problem, or am I just worrying too much again? VP 10. It's in 11l BB AllMix and was watered once at the beginning of the VP with 3l.

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

Leaves problems
Can you please help me ? This little one is week 9, but seem to have a lot of trouble :( Also, I can't find the perfect watering spot. It's indoor with 18L pot, but if I'm watering more that 1L each 3 days, it's wet all the time. How can I do ? Thanks a lot
