So if you're suppose to do it gradually, how come we skipped a stage with mine? We went from Late Growth straight to Early Bloom and skipped the Transition phase.
Because your DDA1 was showing signs of being unhappy with the level of nitrogen it was receiving, and the quickest way to address that was to skip straight to the Early Bloom (1/2 dose), which has an even lower nitrogen level than Transition.
On the other hand, his plants are not showing any significant issues, so a more gradual transition is possible.
