Calcium/Magnesium deficiency?

Leaves from some fairly well established girls in 4 inch rockwool cubes, usually dunked every other day in low-level nutrient solution.

Hello Twodog
If I had leaves that was showing this I would.
Foliar some cal-mag mix with some fulvic acid.
Or even some Epsom salts.
I say to foliar because it is quicker to get what elements that you think your plant is showing a deficiency in.
Fulvic acid is the cape crusader of all other elements .
It can go through cell walls taking whatever is mixed with it.
General hydroponics has a Cal-Mag solution made from calcium and magnesium carbonates.

On another note, removing leaves that are just starting to show deficiencies is effectively removing a resourse from which your plant is using from those leaves. Now that those leaves are gone, the plant will pull form another leaf compounding your problem. Wait till you get your problem under control before removing leaves if you have to.

Can be, What is `low-level nutrient solution`?
EC? water?
what stage are? the roots have populated the rockwool?

No idea about flubic acid, thanks Ratzilla!

I sure go with e. salts ec 300 µS ph arround 6 foliar, temp 23º.

I have some test to make with the refractometer before and after apply the solution, thinking in how to obtain the juice. Some people say the result of foliar application is big.

I think if you haven't problems with fungus you have nothing to lose if apply es.
