Curling leaves with purple tinge
Had to leave plants for four days. Watered with 1L of water before I left. Arrived to 31c temps and leaves curling with a purple tinge to older leaves. Assuming heat stress mixed with overwatering. Thoughts?

Possible overfeeding nutes?
Could someone possibly identify the issue on that one leaf? I had another like that a bit worse that where the edges started to curl. They were fan leaves so I ended up removing them as they were a bit worse off. Doing much better now, only guess is too much nutes.

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

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 :)

Should I be concerned about the purple spots showing on the freshly sprouted seedling? What could they mean? And when should I start looking to transplant ? And what would be a good height to start training the plant with garden wire?

Deficiency help
What 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.

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?

For a couple weeks there has been some redness in the stalk which I’ve thought nothing of. However, today the edges of some smaller sugar leaves have started to turn purple. Temperature is staying as noted above, should I be concerned?
