help! curling on margins!

[Size_matters]

leaves on my babies are curling on the margins. it doesnt look like Mg def. but im not sure. temp is 75-78 constant. humidity is around 55%

To me it does look like an issue with Mg. That is usually a tell tale sign when the leaves are curling on the edges like that. I bet someone else will chime in here with a second opinion for you.

looks more like phosphorous def to me normally if its mg def the whole leaf will taco up as they say frim the middle of the leaf and start praying....they cup up in a V shape.
phosphorous causes that edge curl along with water stress...normally too much wate
