Gold spots starting in the middle of my leaves working outwards. Any help is appreciated.

Hey yall new grower here. Been at it a couple of months and recently got some new strains from a friend of a friend.

I'm indoor, growing in soil, filtered water with a pH of 6.2 - 6.5. Temp stays around 78 and humidity around 40. And my lights are Mars Hydros FC-4800

I recently started seeing some spots on the plants after about a month of having them. They started off looking kind of gold but as it progresses has turned yellow/brown. I believe it's necrosis but it's started to spread. I thought it was a cal-mag deficiency but I'm not sure since I'm reading so many different things. Took these pics for the forum but I wish I had some of when it first started. Some are on top leaves and some are on bottom. The inconsistencies in the progression is wild. Any help is much appreciated

Is there any calcium in your fertilizer or water?

It very much does look like a calcium deficiency. I found a picture online for comparison. Can you give us a run-down on your setup and what your feed schedule is and what nutrients you use.

I also think there may be some magnesium problem too.

I'm using cal-mag from Botanica. I wasn't at first and I think that was the issue
