What can you tell from a leaf

[mclovin81]

400hps, aeroponic, technaflora nutes, 4gal in res with airstone to provide o2. roots are 95% white with a little brown from the veg stage the roots are about 14 inches long and about 1 inch of them are floating in the res water. right now 10 days into bloom. I would like to apoligize for the additional post I did read the post on Cannabis Plant and Pest Problem Solver - Pictorial

but as a newb would like every comment I can get to reasure me... after checking out the former post It looked to me like a calcium def.

here take a look.

see how the leaves are folding lenghtwise

and last

are the small yellow spots something I should worry about. I added a little bit more BC boost for the added calcium

thanks to everyone who has responded to my post exp "The Weed"
