Hi Growers, my tent has recently hit some low temps at about 15 degrees lights off, I have now improved the temps by a few degrees to about 17 at lights off. Purple is showing on my stems probably caused by cold but purple also showing on the back of leaves? Should I worry?

I would say that it is not an issue but your plants are young so yes it is a problem . The pirplelish colour is due to the low temps and the fact that the leaves and the petioles turns purple is not uncommon with you temps, the new growth will look a the same if you have no way to change your temps to something higher. Any temps under 17 and higher than 30°C can slow your growth. From what I can see you are now at the lower temps limit ( don't get back to 15°C ). You did worry enough now you can relax 😊

Leaf discolorationThere 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?6y ago

2 part question about harvest and flushing. I read that if most leaves around buds are turning color (purple in my case) you need to harvest soon before plant dies, is that accurate? If so my runoff is still the color of an ale after 3 weeks of flushing, is that normal or bad?Week 15

Deficiency helpWhat deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think.
Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.

Autoflower Selective Harvest?Should I do a selective harvest on an autoflower? My plant overall is pretty uniform in height outside the main. Is it safe to harvest so that I can drop my light to give the rest of the plant the light it needs to finish strong?

Some sort of deficiency?I'm thinking it's lacking phosphorus, but this is a first for me. I gave bio nutrients yesterday, which also contain phosphorus. I've read that bio nutrients need a bit of time to become available to the plant.... Any other feedback is also much appreciated

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?
