Early Calcium Def

[burrr]

I'm pretty sure that this is calcium deficiency at its early stages. These are clones, just transplanted into dwc.
Anyone agree? I believe the condition is getting better, but the leaves will continue to get brown spots where they have light spots now.

Incorporate some amount of tap water into your reservoir. If it is in fact Ca deficiency the calcium carbonate in tap water should clear it up quickly.
