Nutrient Problems?

I was watering my plants and noticed brown spots on some leaves, some brown tips, and some had brown edges. I'm very new to growing and not 100% sure what the issue is. I am using Gaia Green All Purpose 4-4-4 and Gaia Green Power Bloom 2-8-4 with Worm Castings and Fox Farm Coco Soil. I added the mix on November 1st and switched the lights to 12-12 on the 6th. Today on the 11th I added 15 TBSP of bloom and 1 TBSP of veg to see if that will help. I usually water 2-4 days with PH 6.5. I believe it to be a Calcium or Magnesium deficiency. If anyone knows if that is what’s wrong or if it’s something else, any advice on fixing it will be really appreciated! Thank you!

15tbsp is for how much? And how much you have? Pic of whole plant

I added 15 TBSP of the Gaia Green Power Bloom into the 5 gallon pots I have my plants in. I already had transplanted these plants into just the Fox Farm Coco and was using the Fox Farm nutrients. I didn't like the result I was getting so I switched to the dry nutrients. I top soiled with 3 TBSP per gallon but was told it wouldn't be as effective as it mixed into the soil before transplanting. So I thought it could be the lack of nutrients that were in the pot so I added more in today.

They all look like they are starting to burn.maybe you put too much.

Thank you for the help! I should've held off on adding anything else haha. Very new to this so I really appreciate the help!

Take pictures in regular light. However I believe I’m seeing magnesium deficiency and likely potassium deficiency. But don’t go off that until you post better pictures.

Yeah, I agree, probably a little bit of Burn.

16 tablespoons or 1 cup is a lot to dump on top of a 5 gallon pot all at once. I would use like half of that for a 7 gallon pot. And your plants are really green and leafy and healthy looking otherwise, so it's probably not a deficiency.

I think you've got tons of nutrients available, so I wouldn't add anymore. As far as fixing it, you'll probably just need to wait it out and chill. Maybe add some kind of microbes to try and balance things out in your coco.

If it gets way, way worse you could think about maybe removing the top 2-3 inches of soil that you mixed the dry nutrients into. But I would only do that if they get uglier.

Appreciate everyone's advice! This is a little update. Went into the tent today to see how the plants are doing. I still see browning tips, edges, and spots. I also noticed some of the top leaves curling a bit as well as the soil being real hard, almost like concrete. I did add Perlite into the pots on the 11th when I watered. After loosening up the soil by hand, I thought this could be because I had too much soil in the pots so I removed about 2-3 inches of it.
