Blackening leaves on 2 week old seedling.
furphy
started grow question 6y ago
Any ideas what has caused the blackening on the leaves? More effects of the overwatering? Hope it's not a lost cause but I'm losing hope.

look like microfungal, you water it a lot?🙏 Before you undo ... try cutting those leaves, you might save the others... luck bro😃

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

Leaves are getting dark
Leaves are getting a little dark and cotyledon seems a little sad. I suspect it is caused by not watering her enough (i was only spraying her with water the first 4days) Any advice?😀

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Listless plant
What would cause this specific plant to look so droopy and sad? Had to cut out some totally dead growth. I’m at week 7, is it too late to help it?

Weird coloured leaves
The leaves are yellow a bit on the outside and just today noticed that it looks kind of black too. Anyone know if this is because of a certain deficiency?

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.
Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.
