Is this too much potassium?

I'm in my 5th week of flower in soil, and I'm feeding my plants maxsea bloom (3-20-20) once a week along with humboldt nutrients bloom booster ginormous (0-18-16) and I'm going to start giving them snow storm ultra
(0-0-3) to help boost resin production. My question is if it's ok if I still give them molasses along with everything else or is this going to cause potassium toxicity?

why would you give them both a 3-20-20 and a 0-18-16 at the same time/ the humbolt is a pgr not a fertilizer you should read a book or two
