I would definitely invest in a Guardian BlueLab to line up your PPM. The mixing you've described seems to carry too much nitrogen, possibly. I use tiger bloom also, and for my mixes I like to get it to around 600-800 parts when flowering, with alternating food then water every other day (usually when they dry out). Also make sure you are letting them dry out a bit, then flush those mugs with 6.1 water last 2 weeks.
My blends are usually around 1200ppm when vegging in basic promix HP with earthworm castings, and flowering around 1700-2k ppm but my water always stays around 5.8-6.2 ph. To my understanding, there is more nitrogen in soils like Ocean Forest and Happy Frog, so you have to be careful with your flowering blends when using those types of soils. They usually don't need a heavy blend of food.
