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 😐

Brown Edges on Leaf. Bit of yellow and purple.What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

Is this turning purple from temp changeSo it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Braune Flecken an den BlätternHallo zusammen,
Ich habe seit ein paar Tagen diese braunen Flecken auf den alten Blättern meiner Pflänzchen. Die Wochen zuvor habe ich gedüngt, allerdings nur mit 1 ml BioGrow, 1 ml BioBloom & 2 ml CalMag von BioBizz — denke eher es ist ein Mangel.
Vielen Dank für eure tips!

Brown patches on leavesNoticed these marks on the leaves of the plant I've had problems with.
Any ideas what they could be?
The other two are smelly amazing and the single plant is so sticky! I think it might be the cheesecake but I'm really not sure, I won't make the mistake of mixing them up again

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

My lamp is now something like 80cm away. And I hvn't watered for 1 wk (but soil still wet, so... I wait ?).
=> Should I remove parts of leaves ? What about leaves with center dots?
Previous question for more info,
Thx

Yellow leaves - moby dickThe olders leaves started to die and to turn this yellow-brown color.
I thought it could be the temperature (I am about to receive my temperature hydrometer to measure that), or over/less watering, or nutrients.
The plant looked great a week before.
