Brown black spot crispy edges
lovely_neighboursstarted grow question 3 years ago
I need help! Northern Light has Reddish brown spots turning dark-gray and crispy dark edges on the top leaves! It looks like a different issue from week 6 where gray spots appeared on the bottom leaves? Any ideas? Thanks

Looks like you have or had a calcium deficiency. When you grow under led lights the plants need more calcium. Best of luck the rest of the way.

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

I'm not worried at this point, just really want to know what's happeninga month ago

could this be due to the PH being too low?I watered 3 days ago with PH 6.3 Ruoff was 6.0
today watered with PH 6.6 runoff was 6.1
Can the brown spots come from the wrong PH ?

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

Strange Twisting LeavesI have a plant that's just over 3 weeks old, and since the first week or so, I noticed it has some leaves that grow with a "kink" or "twist." They all seem to have a small discolored spot on the edge of the leaf that eventually becomes the corner of the kink/twistLeaves. Edges burnt

A deficiency, a toxicity and a toxic-deficiency???Here's what I make of it (and PLEASE correct me where I am wrong!) :
The tips yellowing indicates, a nitrogen burn.
The burnt brown tip indicates, nitrogen burned to long 😂
The black spots indicate, a P or K issue (as the leaves are otherwise healthy green in color)14 days ago
