magnesium deficiency day 14 of flower

I have a mag def I can't seem to get under control. Do my buds look like we're they should be for 2 weeks in. Do the last 2 pics look like burn? I just fed with 600 ppm bloom nutes So I don't understand why they would show signs of burn

Here a couple clearer pics

the second picture is probably from spilling your fertilizer on the plant when you were watering I don't think you have mag deficiency. I would water with veg nutes (not bloom) to get them greener. During this two week transition from 12/12 flip it is normal to use veg nutes.

I was using cns 17 grow till just recently when I switched to bloom I didn't wanna have too much nitrogen built up so u think its a nitrogen def

The leaves look pale green, if it were me I would hit them with Grow next time you water. Then after that stick with Bloom.
