Curling blueberry leaves????

I don't understand why my dutch passion blueberry plants leaves are curling downward to make a claw i have them in a TFL hydro system with numerous other strains as well(whiteberry g13 mango hash plant) all the others are doing freakin wonderful but the BB's from 3 diff mothers are all curling down, i am using advanced nutrients, i have the whole line of it,the room is AC'ed at 72 F and they have 2 600w hps lights, i know its not to hot and i have a trimeter for ph/temp/nutrients with everything norm, its almost week 5 of flowering and i just dont get it the big fan leaves are starting to curl as well but the leaves around where the bud forms are f ing curling like crazy , the color of them is a nice dark green with no signs of being "burned" , any help ?????? i also was reading around and it seems common in blueberry but im no pro. sorry i cant get a pic on here because of legality reasons but i have been very descriptive please someone help me.....?

wheres my post?.... or does it take a few to show up

you should be fine, blueberry is a fucked up strain to grow.

also not much flower production either , just a bunch of leaves curled downward like a dead spider's legs

Im not sure if this helps but sum strains are picky about there environments and tend to grow well in a climate that the genetic mother grew in. U could get a strain that grows great in a dry hot environment or a strain that grows better in cooler more moist climates. I suggest trying different temperature and humidity levels. But then also u risk makin the other plants leaves start curling heee. Oh well thats my 2 cents. As for flower production ur only about halfway done , need a good 9 weeks.

yeah guitarman , i kinda suspected the same , the seeds came from the europe and im well i cant say but it is tropical year round even when its cold , so maybe thats the issue , ive always heard BB is a hard strain to grow , maybe next round of BB clones ill do organic instead of tfl and just ill the tfl with things like HP, BC ,WB , Mango , too bad though i was lookin foward to some BB , hey .....do you think it was because i got the 10 pack of dutch passion none feminized, i am noticing most of the fem'ed strains i got are magnificentexcept the cheese and blue cheese need more tlc

My Dutch Passion Blue Moonshine's leaves curl too and I couldn't figure out why. After reading DP's description of Skywalker, I think the curling is actually expected as it appears to be a genetic trait to the blue family. This is off of their website, Skywalker description:

"Blueberry characteristics such as “curling leaves”, slow initial growth, and bluish hues have disappeared in this hybrid, while taste, aroma (fruity and fresh), and the quality of the “high” are retained."

If the leaves are very dark green and clawing it's an indication that the fertilizer levels are just a tad bit to high for these plants. My blueberry does just fine.

Do you have Dutch Passion's blueberry? Or some other breeder's strain of blueberry? I'm going to back down the nutes on my next grow rotation as test. I don't want to tho because my Moonshine does the best of all even with curled leaves and plus all the other plants don't have this problem so I don't want to starve them of any nutes. But I'm still going to try it, I'll be able to test in about 2 weeks or so. I'll hopefully remember to report back lol.

Dutch Blueberry likes light nutes. I fed mine twice or at times once a week (soil). 1/4 stregnth and work your way up to their response (Hydro). Good taste, different grow, and medium harvest if your light on the N. Better in soil so you can keep water and food intake to a min so it remains bushy. Good luck.
