Hey guys see week 13 day 90 last picture is it Mag...
MomnPoppaSeedanswered grow question 5 years ago
That's exactly what mine did with a cal-mag deficiency.
I thought it was light burn although it wasn't close enough to be.
But when I asked i was told to try a cal-mag supplement and it worked like a charm.
I'm new too but I just wanted to say that mine did start out with 1 like that and got more within day.
Good luck, she's pretty otherwise and the one I had do it is now my most beautiful plant to date.

Could someone help me to identify the issue my plant has?This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.Leaves. Color - Yellow

Dark purple areas on leaves — genes or environment/feeding problem?What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors?
I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐2 months ago

help in Hydro RDWC/DWCHello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds
They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?Leaves. Curl down
