Brown spots on leaves. Can this be because of too high pH of the water (7.5)?

Possible manganese deficiency?
I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

The 2 spots on the front leaf and the dark areas on the stem are bothering me a bit. Do you think the plant has a problem, or am I just worrying too much again? VP 10. It's in 11l BB AllMix and was watered once at the beginning of the VP with 3l.

What’s causing some of the leaves to look like this? Is it a deficiency or excess? I was watering with 1000 ppm, but I saw some burnt tips and dark green color on the leaves, so I gradually lowered it to 500 ppm, and today I noticed those spots (the drained water is at 750 ppm) (coco and perlite).

I just found a spot that is making me think bud rot. I so hope it's not true. Slight discoloration of pistols and leaves in a bud node. I added a picture in this weeks section. Please tell me it isnt bud rot.

Brown Spots on Leaves
I've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.

Crispy brown leaves
northern light is showing yellow and brown leaves at the top and the bottom of the plant. These leaves are thin and crispy like if they are about to fall off. I am watering it 2 to 3 times per week and started adding a bit of cal mag last week when they started showing brown dots

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Late Flowering Stage Deficiency or Nutrient Burn
I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.
