so, in final analysis of my own question, with continued research besides the post. and just to sum up the post in my own words for clarification.

there is probably to much root matter in the bucket,
? so when the plant is fed,
and then fed too often,
the uptake of the nutrs is very efficient, too efficient. ?
it is not a deficiency as first suspected.

? the roots are taking up the water/nutrs
and they are getting extra nitrogen...
so this is making the leaves curl down ?

this example of leaf eagle claw / leaf canoe droop
on healthy bud site leaf families. is a result of
extra nitrogen uptake from a root bound system,
it is also cold on the roots, so ? ...
...this is slowing the plant growth at the flower top leaf ...

so maybe there is extra nitrogen there
that the plants could use
but are not able to use most efficiently. ?

there is not enough soil matter for proper plant function ?
which is only being amplified by w.constant
cold concrete during night cycle...

no need to worry about a flush so much as
the soil environment to root matter ratio in conjunction with plant uptake of and frequency of feeding and nutrs.


otherwise healthy plant
( over fert./ bound root system + cold = specific claw )
