They look okay for greenhouse. Could just be smaller or slower plants? Also does the fertilizer call for 6.8 pH that seems a bit high?
 
Im using earth juice ,can be acidic..my pH was lower at start of grow added a small amount of lime to adjust..out of twelve pots this one is showing the curling up and yellowing on the leaves except the veins.humidity has been high on some days..it's a dj short blueberry,and I have two others that do not show this...

Are you bubbling it first?
 
No ..but the 11 other plants are doing fine..would not bubbling cause one plant to yellow outside margins and curl up?

Well if the only ones doing it are the ones you added lime to, the lime would be my guess. But I don't know what all you've got going on. I had some super tasty frosty buds when I used EJ. I bubbled it everytime with a handful of EWC and some Hi-Brix molasses though. It does have a pretty low pH to begin with. Bubbling helps raise the pH a little.
 
Could just be you got a runt. I will say I grew the same strain earlier this year and it required separate feed than my other strains. In particular I had to feed the blueberry heavier than everything else to not get yellowing on leaves, especially lower leaves. I see some weird twisty growth on some of the leaves I'd get a microscope pop a few leaves off and inspect the bottoms for pests.

No I limed all the pots ..to adjust after 4weeks of sugar peak..ph was getting down to 5.5 and EJ is acidic so I adjusted...the curling up is what's got me confused because pro mix hp is so porous and they are in 25g pots and never give more than a gallon each per day..

Thanks I'll check..the yellowing is faint in pics but it's just outside veins and the veins are dark
 
Leaf curl can be from a couple of things.

1 nitrogen toxicity. Which I am not seeing here.

2 higher heat than what the plants like. The most likely culprit

You're not doing that right.

Looks like minor heat stress to me and one out of a bunch of plants being different is pretty much the norm. Could be getting more or less wind where it's at or just a bit hotter for it. Might just be fussy like a few I have going on. :)

:peace:
