Someone please help!

Leaf tips on my plant started going yellow so I just gave her plain water, then a couple days later this appeared.

This is the pic as it is now however I don't think it was as bad when it first appeared. The leaf is curled at the top and cupping.
I didn't make a connection between the two things and I assumed it may have been against the window sat in condensation over night.
But now it seems to be starting on another leaf aswell.

It almost looks like light burn but there is no chance of that as it is sat in the window in the northern hemisphere. It has been a lot sunnier the past few days so could it be the sudden fluctuation?
Or is it some kind of deficiency? I have compared it to different deficiencies but it doesn't seem to be. Any help appreciated

Looks like classic overwatering to me. From my experience, light burn usually manifests itself in yellow spots on the central areas of the leaves and yes, potentially the tips. However, in the pictures shown the yellow curling is exclusively at the leaves, the leaves are drooping and they are a very rich green colour.

95% certain it is overwatering - same advice I'd give anyone, don't be afraid to really dry them right out so the pots feel light as a feather.

Lets see the rest of the plant.

Seeing your bottom photo.
Harvesr is any day soon anyway.
The plant will drop its fan leaves while it ripens.
Wouldn't surprise me if thats whats happening.
Imho start fading it out for harvest.

I second that judging by the amber trichomes on that bud indeed.

About how long would you say until harvest I don't have loop or anything so if you could give me your best guess would be perfect. Not watered since i posted and whole plant looks droopy so pretty sure your right why. Either way if anything happens I'll just cut it before the buds are effected.

Its subjective.
You could harvest any day now. But I would fade it out.
I like to flush mine, when i feel its ready to chop. So i wait until it looks (AND SMELLS) ready. Then i starve her. Until the fan leaves are yellow, and falling.
Then, chop, hang, cure, smoke it

Id be starting the fade now.
To harvest in a week. Or just over.
Get that fade going on your big fans.
