Day 50 Flower brown curling upwards leaves

Today is day 50 of flower I have done everything the exact same for these 2 but I'm getting different results, and I'm trying gimp theses 2 babies to the finish line.. The first Female doesn't look to be in to rough of shape has nice buds coming from her.. My second girl has Problems brown crunchy up curling leaves everywhere and doesn't seem to be losing its white hairs as fast as the other one.. I've done research and think it's a phosphorus deficiency but not sure..I used the liquid plant food Big Bloom and upd the newts in it but with no success.. any tips or suggestions i am open to...

Problems

phosphorus deficiency doesn't look like that, this is just straight up nute burn. Big bloom is just a supplement? what else are you using? there is not much that can be done at his point in the flower.

agreed, its nute burn.

X3 on the nute burn
You can see the starting of N toxicity in the leaves also,
I’d flush before you get total lock out, get the ppm’s of the run off down, keep running ph adjusted water with a very low ppm till to get the run off in check,
Once that is taking care of , cut your feeding way back, and if your not using one now get a ph & ppm meter so you know what’s happening in your root zone, and what levels your feeding , and you can montor the rate they need more food and when to up the dose.

Sometimes less is more.... each strain will act differently towards your nute line. Def flush with plain water if not once but twice. You won't lose out

Thank you everyone for the info. I've been flushing for 2 weeks now looking a bit better.. 1st time grow but definitely learning alot.. next grow will hopefully go lots better! Any other advice I'm all ears

How much longer do you think I have?

My guess is another 2 weeks and a week in total darkness? Any guesses?

A week of total darkness ehh?
Id say a week or so

Just something I've heard that helps to bring out the last of the trichomes..Not something you'd recommend?

A week is the longest I’ve heard anyone doing this.
I can not do this because of setup,
But from what I read 48 hrs seems to be the best.
Cut a bud just before the light is supposed to turn on, do 48 dark cut a bud etc etc
Label n write it all down . Come up with what u like.
Harvesting at peak ripeness and proper
Drying & curing are more important

Sativas are very finicky feeders. I would let it dry out and if you leave in dark for a week expect mold
