I have no clue?

Does anyone know what this is and what is the cause of it? It is really starting to worry me.

How old is the plant and what stage is she in?

looks like a calcium def.

is it all over or just on that leaf?

Try spraying it with hydrogen peroxide. It works on damping off,powder mildew, mold and mites don't like it.

looks old. Is it growing?

What soil is she in and what nutes are you feeding if any? What are your ph levels, feed water, soil and run-off? What are the temps and rh levels? Some of these are not as important as others but most are needed to diagnose.

Hello all, Well I will write what I do know about it. It is a strain called "UW, or UDUB". I cannot find another one to compare it to. I was given the plant in a very small form. It was all just beat to hell. She has come so far. I have measured and she has grown almost 7 inches in the 3 weeks I have had her. She is in a soil less mix. Unfortantally I got her at a really bad time. I had no where for her except the cold garage. Yes it is really cold. But for some reason she is thriving out there. I was undecided about keeping her but she has grown on me and I bucked up and got her a tent and all the supplies needed to make her happy. I have just been watering her and didn't have the proper food. I got some today and hope she perks up. I would say that she is about 3 months old? I really don't know. Water ph was around 8 I think. I have it at 6.3 now. The spots are only on maybe 15 leaves and they don't cover the whole leaf, just little spots here and there. I do thank all you guys for all your help.

Well, still no where near enogh info for a definate diagnosis. However, you did confirm one of my thoughts K deficiency due to high ph and cold temperature. Without more info the best I can offer as far as how to correct it is to flush her with about 2 times the water as you have soil, get her warm, 74-84 degrees is a prme range. That may clear it up. Good Luck!

Very possible as well.

I dont see any bugs. It really only appears to be on the bigger older fan leaves. I really don't know what is going on. My water is 6.3 now. I started feeding her some gh last night, Florenova. and some Root something.
