I would lean more towards magnesium. Won't hurt it to add a cal mag supplement to your nute line. Other then that she doesn't look too bad.

I think it's the early stage of calcium deficiency. Increase the distance between the light and the seedlings and add calcium as well.

Deficiency or toxicity Stems are really purple, leaf stalks and veins also purple. Something is up. Some leaves starting to show burn spots but not many. She's a bit down because she needs a feeding. Is this magnesium deficiency? Should I be upping my nutes at this point this late in veg end of W9?

Leaf Septoria is it worth treating it if it's on an extra plant or should it be culled I have an extra plant outside my grow cage and it has leaf septoria. It was neglected to begin with. Is it worth treating with copper based fungicide or should it be culled. I have no experience with this. Someone please help.

I was late watering one night last week and she was looking wilted, then 48 hours later, she looked this like with all fan leaves wilted or dead and crispy and she isn't standing back up after watering. Nute-lockout? Underwatering damage? I always check nute pH. Thoughts?

Top of plant chewed off I woke up this morning to the top of my Passion #1 seedling chewed off by birds. Is still worth growing? I can't imagine the amount of stress that plant endured. It's a rare strain so I'd like to try and finish it but not sure if the juice is worth the squeeze? Thank you!
