browning hair tips

So..........This is my fifth crop and the best yet. I have never done this good I am using cutting edges nuts with a 1000w hps, and my girls couldn't look any healthier.
But a couple of days ago I started to notice my hairs(petoiles) turning brown on the tips. Now I that this normally means the plant is reaching maturity but this is impossible for me right now. I still have at least three weeks left to flower and the hairs should not be turning brown yet. So today I watered with just water but when I was using nutrients my ph was 4.5-5.0 which is low but I use calcium so it creats a considerably low ph then rises as the plant uses the calcium. My temp never rises above 75 degrees and my light is two feet above the tallsest girl so it is not a burn from heat. But if it is a nut burn how come it is just now showing up? And if I just start using water, well flood my system, will it go back to normal?
Any advice would be great! Thanks, Irie!!!!!!!!:rasta:

lost, did you spray anything on the plants?

: )

No I haven't foliar feed since veg. which was four weeks ago, I haven't even sprayed just straight water. My humidity isn't low at all if anything it is too high my humidity ranges from 50-65 when the light is on which is good and when my girls are sleeping my humidity can reach 80 which is the highest it ever gets. I was talking to my mentor and he said maybe they are just going to turn quick but this I don't believe because the buds are tiny and it's only been four weeks. I have white widow and bubbleberry. The widow I have grown before and it took eight weeks and the widow is the one that is browning. My trichomes are going crazy right now though. So again I just watered with straight water. What do you think and thank you for your responses!

Yeah but have you ever witnessed something like this? Do you think I should stay away from the nutes and just keep using water?

Is this what you are talking about...?

isn't any percent above 50 a potential treat to mold of the flowers.just want to be sure anything bad happens to your girls especially this far into your grow

ya 50 % during mid to late flowering.
It sounds like a little over heating or low humidity combined with maybe a thirsty plant.

yeah knowm kind of like that, but some hairs are completly. Yeah the humidity being so high for so long at night has now created powder mildew, hahahaha.......Go figure huh! You know what they say " you learn something new everyday!"

Dilute some lemon juice spray your plants and try to kill the mold before harvest.
DFG

Lemon Juice, even diluted, is one of the best resin dissolvers known to man.

I wouldn't touch a resin producing plant with it. Lest your resin run and drip off the leaves.

Sulpher cans is your best shot.

SULPHER...

even though I hardly know her
