First time growers (after first crop)

What did you learn from you first grow and what are you planing to change next time?

For me everything went great until about the 5th week into flowering. I started to see calcium deficiency with yellowing leaves and brown spots. A was able to correct it and ended with 1.75 lbs from 4 plants.
I was using 50% strength on my feedings the entire grow, so the next time i plan to still use 50% but bump up the calmag to 100% starting week 3 during flowering.

Experienced growers would this be a good idea?

I use cal mag regularly from the start. Even running municipal tap water. Calcium is extremely important in all phases of growth. Being mostly immobile it can't be pulled from older growth by the plant like nitrogen can.

Cal mag has nitrogen so adjust accordingly on Grow. You can overdose them on calcium and cause nutrient lockout. I give a dose about every 3 feeds.
