It seems calcium deficiency to me. Nothing to worry about. You can fix it with adding more cal/mag in your feeding.

Slight nitrogen toxicity and possibly the start of a slight deficiency of calcium, easily fixed with extra cal/mag in your feeding line up.

Your plant has a calcium deficiency, you've got the curling tips and the small brown spots.

yellow/copper appearance in some leaves after first run off watering
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?

Color of top leaves
Small question about the color of the top leaves, is it a lighting problem, or something else? The leaves on the lower floors do not (yet) have this color. I'm thinking it's genetics but I'm not sure. Thank you

Brown leaves and red stems. Is this a calcium deficiency ?
I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!

Red petioles, everything else good
Hi! :) Does anyone have suggestions on the red petioles? They all turned red in flowering week 3, also the lower ones. I removed the secondary shoots and some leaves lately. Nutrition should be plenty, soil pH and EC are normal. temps are normal, humidity in a perfect range...

Lack of or abundance of nutrients?
Shes doing really well but I noticed some of the leaves starting to get a little yellow so I stopped giving her nutrients and have just been giving her water for at least a week or two. She still acts like shes getting too much though? GDP auto x gumberry auto is the strain.

Bruising or nute problem?
I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.
