Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

After last question with those symptoms, I flushed her with pure 6.5pH water, then next time started to adding only Biobizz Fishmix, and another next time I started to add all nutrients again but 50% of recommended. Buds, the white ends of the flowers begin to turn brown as well.

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!

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?

Is this more nutrient deficiency?
I believe the yellowing and brown spots came from the roots starting to suck up more water than the previous weeks. Do you agree that the Durban Poison had some nutrient deficiencies?
