Indoor, hydro, blueberry autoflower plant

Second time grower. Autoflower and hydro. I am using a “zero water” filter to remove dissolved solids down to close to zero before adding nutrients, adjusting ph, and checking PPM.

My leaves (week 5, flowering commenced) have blotchy bronze/brown spots which I have read is probably a calcium deficiency. I have been using 1 tsp CalMag/gallon of water, and change my water weekly. 1.4 gallon aerogarden setup.

Since the brown spots persist on new growth after a while I assume I am not using enough CalMag since I am starting with RO type water that has zero nutes in it.

Thank you in advance
