Curled up leaf

[flamstaa]

Not sure what this is. It's not excessive light, They were showing this under flouro. It's only one strain and not all plants of that strain are showing this but these babes are not growing as well as the ones that don't have this leaf curl.

 

I should add these are from femeinised seeds I made myself

Any theories or explanations?

Yep, reasonably humid but not OTT. Plants usually love humidity in veg.

 

Just read on another forum someone saying Mag deficiency which they're showing a hint of

It's the middle leaves curling, not the top ones so I don't think it's heat or excess light.

 

They were also doing it as seedlings under flouro. The 600w they're under is more than 120cm above the canopy and the temps in the tent are quite reasonable

Me too!

 

What are you feeding them ?

A + B coco specific nutes with 1/2 strength cal/mag supp and Seasol @ 3ml per litre, EC 1.2.

someone mentioned yesterday in that pythium thread about seasol not being a nutrient ?  I got no idea, but might be worth researching, everything else seems fine.

poss build up of light , heat or humidity , reflection from walls & other plants , leaves reflect light , could all build higher in diff areas of the tent 

is it poss to swap spots with another plant / has that plant been in the same spot the whole grow 

is the plant in a corner or middle of the tent , is the plant sitting between 2 lights , do you have a circ fan running that's not quite getting everywhere ?
