Calcium def??

Hey new grower here day 22 of 12 12 flip. Ive noticed a few leaves doing this. Its on a couple newer leaves as well as some old ones. Ffof soil with fox farm nute line up. PH stays between 6 & 7. In a 5 gallon bucket and have to water every 2 days. About 2 weeks ago my PH dropped to 5.8 so i top dressed some dolomite lime in to help. I know it has a good amount of calcium and mag in it so i stopped adding cal-mag to my water for now. Over all she looks healthy and id like to keep her that way. Temp stays between 73-79 all the time. Humidity 50%-65%. Im thinking calcium def but im no expert and the pics off the def chart are hard to compare (yes i did check there first). Pls help.

She looks strong with dark color. You're on top of everything. You've checked and double checked. PH and temps are good. Vibrant growth.

It's a good looking sativa. I'd leave it alone and not over correct anything. Plants don't grow perfect. Overall, it's a pretty plant.
