Dark spot on the leaves of my seedling
Hello, i have a weird dark spot on my seedlings idk what it is and if i should be worried. I know on these genetics the leaves can turn dark purple but I don't think it would be happening this early. I fed them nutes for the first time yesterday and today this dark spot appeared.

Dunkle Flecken auf den Blättern.
Hey.. On one of my White Widow plants, dark spots have been appearing on the leaves for days, and today I've also noticed the first spots on a Blue Dream.. Can someone tell me what's going on and how I can get rid of it? Removing the affected leaves hasn't helped.

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

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🙏

My seedling doesn't look so good.
This is my first coco grow so could be possible that I made a mistake. The other three seedlings are super healthy but this one has this weird thing with it's leaves. Somebody seen this before? I gave them some root juice and fertilizer before transplanting with ph between 5,5-6.

Hey friends, can you tell me what this could be? Should I be worried? It seems to be doing fine and it's the only leaf with spots, could it be due to some water accidentally falling on it? Thanks

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.
