Need help spotting problem

[Cookiescrusher]

Hello I have meat breath that gets blotchy with spots on leaves before turning yellow/brown then dead.... having hard time diagnosing. Last run buds were bigger by this stage
medium- fox farm ocean forest
Nutes- gaiagreen 4-4-4 and 2-8-4
Pot size: 5gal
Week flower: 4

followed instructions if 1 tablespoon per gal medium... was entering feeding week when it started happening now I am afraid the plant is dying.... added 3 tables spooons more Of power bloom 2 days ago.... have not over watered as i let medium fully dry between. anything else i can do to ensure she doesnt die early? Give her a shot of grow big? Or tigerbloom? will this further hurt its grow cycle length? Please see pictures

Get a second or third opinion, but is that a magnesium deficiency? If it gets too bad you could always do a full flush then start again on the feeding.
