Is this a calcium def?

[Joeypuskin]

Hey guys just looking through the self diagnose section, does this look like a calcium def?

Hey buddy did ya check your ph?
From the pic your diagnosis is right

I'm running rockwool cubes with mini rockwool cubes, ph' the rockwool to 5.2 before start of grow, and always ph to 5.8...hand watering
I'm on to week 8 now, this is only on 1 plant and is not everywhere, just a few leaves.
I'll check some runoff next time I feed
Should I supplement with a cal/mag supp?

Agreed..

pH seems ok so a dose of calmag would be appropriate. Demand for Calcium is high during flower for PK uptake...

1/4 dosage will be perfectly fine. In future try buying a product without and N in it. The bottle you have will do fine for now.
