answered grow question 5y ago
Not a clue could be the start of a macro nutrient defiecany but that would be my best guess im sure she will be fine though not a serious problem could just be part of that pheno :)

Upside down leaf growth?
What is happening to this plant, it seems to be growing leaves upside down? It had nothing come out for a few days and then 2 new leaves started to grow out of it but it's like the top dark green side of the leaf is growing on the underside. Any ideas on what I should research?

Color change after LST
I cut a few stems under my autos before they started stretching. LST has been a part of the game too. As soon as Inmade that move a few days ago, plants begin to have yellow leaves Any idea of the problem?

Thoughts about light green leaves subtle light spots?
Leaves are consistantly light green in color. 3 week old plant, upped nutrient strength to 420ppm a few days ago. There are lighter spots on a few leaves, one is by my thumb in this photo. Others are visible. Does this look like a deficiency? pH is 6. Thanks all for your help!

spots on leaves
There are some spots on some leaves. I don't see spider mites, aphids or thrips. It has been very hot last week, around 35 degrees celcius Does anyone have an idea what it could be? Should I cut the leaves or is it okay??

Rust spots on leaves
Hey guys, please help me identify the cause of these rust spots on leaves. Seems to progress in last couple of days(spread). Might this be a light/heat burn? Or some nute def? I added CalMag on previous feeding. Distance to light is 32cm currently.

Garden visitor eating my fan leaves.
This is my second grow (outdoors) and I need some advice. Saw some holes on the SSH fan leaves. When I flipped one of them over, I found a visitor that I think is a Spider Mite. The grow is looking good but I want to avoid any problems. How do I get rid of them?

Edges of sugar leaves on top cola brown
For two of my plants, the edges of the top colas' sugar leaves have gained some brown color. It showed up shortly after I introduced the grow light on full intensity which leads me to believe it MAY be light burn. I'm also paranoid about bud rot though. See photos. Your thoughts?

[Athens Growers - tap water and salts]
Hello fellow growers! First timer here. Noticed salt residues on top of leafs (D19 pics). They come from the mist maker who controls humidity levels 1) How to treat their leafs? 2) a tap water filter will improve the situation or salts are normal? Peace! 👊

Any training needed
I haven’t trained this plant at all, on week 4 atm. Should I defoliate it, or top it ??? I won’t be doing LST ever, not enough space in my closet...

Yellow leaf septoria?
Hi, I think some of my plants have yellow leaf septoria. How best to treat this? Should I consider removing leaves, plants or maybe starting again. It might of been due to my constant misting to maintain a high humidity at the start or I was also thinking fungus gnats

I believe I fixed my nute lockout a couple of weeks ago. But since flowering has started I’ve been getting a deficiency on the older leaves from the bottom moving to the top. I’m wondering if this is A nitrogen deficiency as I’ve backed off on the nitrogen since I’ve switched to flowering nutes. I’m not really sure how to proceed or if I’m even right.
