Leaves Curling Upwards

[Nesta]

I have never had this happen to me before. I am growing Blueberry in 5 gal. fox farm ocean forest, perlite, Ph at 7, good drainage, temps at 70 lights on, and 66 lights off. AC cooling the room. I used age old grow for veg, and age old bloom for flower w/ some peace of mind guano, and greenfuse stim. Everything great but now at week three the leaves are starting to fold up. It is like the edges are folding up and in on them selves. The plant is still a nice dark green. Any one got any suggestions. I thought that leaves curling up were from heat, thats obviously not the prob.

too much nitrgen.i have the same problem.i have a tendency to give to much too fast.back off a little and flush.then cut the amount of nitrogen.plants will recover in a week or two.also that dark green color is a sign of too much nitrogen :thumbsup:

If most of your methods are tried and true from previous experience then the only factor I would have to assume is different is the genetics. Have you grown out Blueberry before? I have heard from a few sources it can be rather finicky. You might try to drop the ph to 6.4 and up the day temps a bit perhaps up to 80 if I remember the bb being at least 50% sativa.

I have flushed and the curling is still evident. Not sure what is goin on. No signs of burn, and the my other plant at the same stage, and in the same environment has no signs of it. Blueberry can be finicky but this isn't normal. Heres a pic for ya.

Yep you are right that aint normal. I would give the lower ph and higher temps a try.

Is the other plant a BB too?

[Nesta]

well i raised the temps just above 80. I flushed last week, now the curling seems to have stopped spreading,but the leaves that already curled remain curled. No big deal, there under the 1000w and looking great. yep the other is a bb as well

Cool, the reason I suggested the 6.4 ph is that if BB is indeed finicky about nutes and such then I figured the 6.4 would be a better base for primary and secondary nute uptake than 7.0 would. Glad to see they perked back up.
