cessation of growth

On day 60, my northern light plant stopped growing for the past two weeks and its leaves started turning purple. I may have given it plain water instead of nutrient-rich water a few times. What do you suggest to fix it?

hey 👋 its far too early to harvest as a solution, you need to focus on correcting the problem ur plant needs to eat, so give it more flowering fertilizer without delay. Make sure the pH is correct and add Cal-Mag to promote fast absorption. affected leaves will fall one after another, but you should see healthy new leaves growing within 7–10 days

Give her food… mineral fertilizer best way. Organic fertiliser will need to long before it works

The answer to all 4 of your questions is that all your plants seem to be suffering from a major phosphorous deficiency............most likely hungry for potassium too. Nothing to do with "autumn" or defoliation or night temps..............they are hungry for P and K now that flowering is underway. Remember too, what is showing in the leaves now, is a direct reflection of what was happening in the root zone 2-3 weeks ago, meaning these issues have been manifesting for some time already. Keep giving what you already are.............old, damaged leaves will not recover, but the new growth should be ok. At this stage, I would suggest a routine of plain water/fertilizer/plain water/fertilizer as a good feeding schedule until they pick up.

You plant entered "autumn" and should be close to harvest. Next time "Defoliate" a bit and for now: remove all those old dried leafs, they might get moldy if they get wet...
