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?

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.

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

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

Hello, do the leaves of the plants get darker if you give more nutrients before they show signs of over-fertilization? I use Canna aqua. I know that if I give too much nitrogen, the plants get darker. But is it the same with too high EC?
