Leafs Curling Down (w/pics)

well i posted these pics on another thread earlier but thought i should get my own going since i still have questions...

So anyhow one of my plants top leaves are curling down pretty bad and it`s sounding like nute lock/ph problem and i wanted to see if you all agree. my water ph is at 6.0 and i tested the runoff water out of the pot and it was up more around 6.5 ph . . . . so i`ve got some fresh water that`s coming up to room temperature right now that i`ve ph`d down to 5.8. Should i give it a go and flush this baby out?

Also Temperature is 75 and humidity at 51% this is the only plant of 4 that is doing this.

I see you are doing a scrog grow...but I can't tell how you are growing. This is in hydro? Or soil?

If your pH is 5.8, I think even for hydro you are good. But for soil you might want that higher. Just a thought. My pH is always up in low 7s or high 6s, but I grow in soil.

Leaves folding down is usually a potassium deficiency (caused by nutrient lockout, or otherwise). I would get your pH up a bit and see if you can unlock some potassium for your plant. Otherwise, if that doesn't work, give them some bananas (seriously)

I forgot to ask...do you notice any dead tissue? Mostly on the older leaves (toward the bottom of the plant)?

that definately looks like a ph issue. whats your ph ?

Thats realy my dilema... having the same problem... but still wating the new ph meter to arrive. I was reading about it and could be a something like u said ...P def.

Just want to make sure! Here some pics. Do u agree?

Forgot to ask... are your plants into flowering?

And... isn`t a huge coincidence... u have 4 plants and 1 (just 1 is having it) I have 3 and just 1 has the problem?!

Sure they all have the same growmix. Am I wrong? Feeded in the same way? Under the same temp and humidity... and the same strain... This is making me crazy man...

What would u say guys?

I would say that your best bet would be to flush(at least 3x size of pot if in soil) with ph balanced water and see if it gets better. Make sure you give it nutes after the flush since you just took all of them out.

i am doing a hydro setup and i`m growing in coco which i understand usually like a ph of around 5.8 - 6.2 ? i try and keep mine right at 6.0 but today was the first time i checked the run off water which was about 6.5. The water in my reservoir is at 6.0 . i`m using the cana coco nutrients and i also use r/o water. the lower leaves are doing fine, it`s just the very top leaves of the tallest plant. The other three plants in the same system that are getting the same water show no similar signs. I moved one of my fans up a bit to improve air circulation in the upper part of the tent. The plants are getting pretty close to the light. this was also the first week i used the cana PK part of the nutrient regime. i`m thinking this could also be part of whats causing this plant to curl so much. maybe i used it to soon? Thanks for the help yall +rep

17 days into flower and i flushed it with ph`d water a few hours ago lights are off now but hopefully by morning it`s looking a little better. Mine are 4 different strains though so i`m thinking this one is being a little more sensitive to the Pk maybe.

so after reading how did you fix your problem or did you.
