Ww scrog prob

So...I have a WW in a SCROG thats about 2 months old in veg. The other day I noticed two lower leaves, symmetrical with one another on opposite sides of the stem had a bad discoloration. I tried to self-diagnose and the best thing I can come up with is too little magnesium? The problem seems to be spreading to the other lower leaves as well. Anyone have any better ideas?

What are you feeding/light/temp

Feeding with a fert made for tomatoes that is 18-18-21 but doing it super watered down because I have fertilizer problems in the past. Fert has all the micronutrients in small quantities, light is all CFL, and the day temp is around 85. There appear to be black specks on some of the other leafs as well.

It looks like some sort of mold. But ive never seen black specks before indoors.
I know there a leaf diseases that cause black spots, so watch for more and remove leaves asap to prevent spread. Lamp

Thanks for the advice

Hmm, I've seen this on some of my moms before, too, though it's never amounted to a huge problem for me... but I am curious what the hell it is? Anyone? Have you figured it out since your last post, Johan? It sure is ugly, whatever it is....

all it is bro is your lower leaves are under shade from the rest of your plant, your supposed to trim all "salad" from under the screen to protect frrom mold. the leaves are just not getting enought light. just trim them.
