Dark tips
it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

Problema con mi Runtz Muffin
Buenos días, Tengo un problema con mis hojas, (puse fotos para que podáis ver). He visto que podía ser un deficiente de fósforo. Pero también puede ser un problema de calcio y de magnesio. Alguno podría ayudarme con eso ? Que tengo que hacer ? Añadirle un PK 13-14 ?

Leaf discoloration
There is a purple/blue tint to the tips of my older leaves. New growth coming in lighter green. Slightly red and purples stems only at base of oldest leaves. Leaves also taco curling slightly. Thinking phosphorous deficiency at this point, maybe combination N toxicity and heat?

Reason for red / lilac stems of fan leaves?
The stems oft many of the fan leaves turned lilac over night. Not only the top ones, so I don't think it's stress from the light. Could some light defoliation the two days before be the reason? The only other thing I changed were 5ml of bio Hesi bloom nutrients. Otherwise healthy

Leaf underside Veins going purple
So the plant I was worried might have a cal-mag deficiency coming on had slightly more yellow leaf middles and undersides. Tonight those have all started to go a deep purple color like some of her fan leaf stems. Does anyone know if this is common with the Forbidden Runtz?

Hey everyone, my Dark Devil Auto has has dark green leaves for weeks now and is now showing purple under her leaves. Just wanted to know people thoughts? I’m only giving 450ppm to all plants with GHE FloraTrio in line with their feed chart and some bent tips due to small tent!

What do purple/blue marks on seedling's leaves mean
I noticed some purple/blue marks on leafs of my seedling. Yesterday I left it outside for too long and it was colder than 15°C (but not colder than 10°C) for around 3 hours before I put them inside. Did that affect it?

Purple Leaves (not purple bunds!)
Noticed some purple patches forming. Im sure this happens every grow and I end up with a range of answers, but as I'm using some utes this time, I wondered if its more likely to be one answer over another this time. Think its phosphorous deficiency?

Seeing some top bud leaf discoloration
Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity

Leaves dying week 6 flower
Hey growers, I'm at the week 6 of flower, and leaves are dying in some specific spots. Runoff ph was checked, 6.4. Feeding 4ml/L bb top-max & bloom. Bio-Grow was cut off after dark leaves, clawing & burned tips. Does someone know the cause? And how big a deal is it? Thanks!

Purple stems-curling tips leaves point down
Guys the sides stems seem really purple!even the central stem.. Why? magnesium deficiency?or genetics? And that leaves tip pointed down; they are a problem.. Maybe N deficiency?(due the early preflowering for the wrong light cycle) Thanks :)

Why is the new growth turning purple?
Is a night time temp of 15degrees the cause? I can't keep it up without making it too hot, or could this just be a phosphorus def.? I fed her well yesterday and yet to see any difference, as far as I can see this isn't typical for the strain

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 😐

Why is one of my plants turning purple at the top?
One of my plants is starting to turn purple at the top, both leaves and the bud itself(As shown in photos 3, 5, and 6 for week 11). Could this possibly be bud rot or something I should be worrying about?
