Mysterious drooping

So this one has been pickling my brain for a while and need some help. @Dr. Who you seen to know your stuff and this is quite an acute problem.

Only the top leaves and the outer finger parts of the leaves are drooping.

Tried various wet and dry cycles. Currently at every 2-3 days 1/2 gal of water for a 2gal pot. Droops real bad when watered and again droops while dry. Never completely happy. Pictures are of varying stages with the last being the latest between a wet and dry cycle. I noticed a lack of S so added Epsom salts last feeding and she’s greener up on her new growth nicely. Still this bud leaf drooping which is concerning me.

I should note the humidity has been low and that’s the only variable since my last grow my a few months ago which went really well. Was 50% now 38%

Any help much appreciated!

Must have pushed the aerodynamics button accidentally

Other than that im sure i seen some do that flex.

I’ve got some drooping issues to but I’m in veg I’ve backed off the water and feed intervals as a start then if that’s not the issue I’ll start looking ant nitro.. thou I have no variation in leaf colour my colour seems to be ok just a lil droopy and slight curling at tips

Haha - hope not xD

It’s strange. Middle of the 5 finger leaves is straight and the rest curl around getting worse as you go to the outer leaves.

I wonder if it’s to do with the stomata!

It's the low RH..... Bring it up......

Changes your plant uptake of the feeding too. That can effect plant nutrient levels.... It's using more, thus if you are to maintain that low a level. A slight reduction of nutrient ratio to water maybe in order.

At any rate. The plant is passing more through it to help it with the low RH. It's expressing that with the droop.

Thanks for your help! Yea that’s one thing I learned the hard way during flower - burnt leaves but no change in feed stumped me until I found out about transpiration rates and nutrient levels.

Makes sense. Got 1 humidifier running and will see about another. Getting warmer too so that should help with the humidity levels.

Cheers Doc!
