I still have brown spots on the leaves not sure wh...

Looks like Calcium deficiency to me.

Okay, it’s easy to mess up your plants, in a couple of hours you can really screw them up, and it takes time for the plant to repair it self, if you fixed the problem. You have to learn to be patient. She get better, they all way do.

Leaves won't repair once damaged. You are either over watering under watering. Can judge by weight of potter. More potassium in feeding. Is most needed in flowering. Is the deficiency seen

She also looks a bit over water this can create the same issues. try to lay off watering for a day or two an see if she starts to pray to the grow light. Make sure got good drainage.

Is this on the same mid area as your last cal mag/ph issue by chance? If so might be looking at the old damage you have already corrected. Damage to leafs don’t go away an if they where a small leafs when you first caught it. The damage will grow bigger as the leaf gets bigger. Don’t see any purple in your steam an with spot that dominate your steam to leaf definitely would be purple if issues was still on going.
