Calcium deficiency??

Hey fellas, almost all the fan leaves on middle growth has these spots. After the research I made Im thinking calcium deficiency?

that's what it looks like to me. i've had it a few times and cal/mag takes care of the deficiency. GL

Yea I added the liquid fertilizer yesterday that's supposed to have an even amount of nutrients including calcium, Im using Biotabs kit so I dont want to add other brands nutes im afraid i'll mess it up then.

We'll just have to wait and see if there's gono be spots on new growth

Cal def is correct...It's minor at this point....
I would still add a Ca/Mag product! At the least at 2.5ml per gallon! Then up to 5ml if need be...
The available Ca in nutrients is almost always low!
Botanicare "KIND" is formulated with EXTRA Ca for the hydro grower using RO.

Thanks for ur reply. The thing is im using Autopots and Biotabs which is an organic nutrient line. I only added the nutes in the soil in the beginning and havent added anything else after, except now I added the liquid fertilizer and some beneficial bacteria which is instructed to add only once per pot on the full cycle. So I wouldnt like to start adding hydro nutes
