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

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Flushing don't seem to solve my lockout
It's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout. I flushed 2 days ago but she keeps getting worse. Am I being impatient? I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

I've read that it's a boron deficiency, but I'd rather be sure.
