Any ideas or help on cal-mag deficiency in flowering

Had a plant that looked like this . Put aome garden lime in my soil and fixed her right up

I’m assuming your soil is locking out the calcium.

A decent pH meter/pen is pretty necessary for most grows.

I know extreme makes a foliar calcarb, but I wouldn’t foliar during flower.

You really need to find a way to accurately monitor your soil pH. Otherwise it’s just guessing.

Yea man that Vivosun pen ended up being a bad buy like my lights. Live and learn going to pick up a new pen today. Did apply lime to my one plant that looks bad and did a soil test this morning and looking like I got it back within range.
Same soil after application.

I’ll post some finish shots here in the future.
Thanks guys
