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?

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?

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?

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.

Is it time to flush? , could I benefit fade from flushing at just the right timing?
When a plant genetic says 8 weeks. Does this mean 8 weeks and chop. Or 8 weeks and flush. I'm still confused as this is only my 2nd grow. reason I ask is I'm experiencing a lot of fade. Ihave kept my ppms very steady. So I'm sure it's not deficiancy creating this at week 6

All my plants have purple stems on the leaves at this point. They look totally healthy besides that. Not sure how to resolve the issue or if it is not even big deal. Just don’t want to negatively impact yield. Any advice?

Leaf colours
Some concerning leaf colours beginning to emerge.I suspect it is some kind of nutrient deficiency, which I accept as I'm not feeding, but would be good to know for sure all the same. Weird that its just on the one plant despite them both having in the same growing medium etc

Purple leaf
The tips of the leaves are turning a purple color, should I be concerned and harvest now or can I wait another week? This week the water is just water.

Lila Blattränder normal oder Düngeproblem?
Auf den beiden Bildern sieht man an der größeren Padawanin lila Blattränder an mind 3 Blättern. Die Kleinere hat nichts. Grund zur Sorge, zumal die Blüte ja noch einige Wochen dauert? Oder alles peng und einfach abwarten Gedüngt und gegossen werden beide ja identisch
