You don't tell us what your Ec is and knowing the GHEFlora series formula I think your nutrient amount is lower than require: you need to give 0.25ml / L of each ( bloom , grow and micro). It is an under feeding to me
Don't cut the bloom nutrient : flora series is a 3 part nutrients so you always need the 3 parts , only the amount per part will change during the different stages of the grow 😊👍
