Going to use technaflora BC boost and bloom and Calmag for starters. I have advance nutrients aswell but I'll probably use that on the pineapple express just to see if there is much difference in growth.
After doing some research on FFOF its rather common to get nute burn because the soil itself has enough nutes to feed it alone. They say 4-6 weeks of nutrients. I would have to gradually increase the input of nutes. Starting with 1/4 strength of recommended dose first couple weeks.
