Athosanswered grow question 7 years ago Although you are "in flower" due the change in light schedule, the first 3 weeks have an explosive vegetative growth, that'a why it's called preflower / stretch. So yes your plant will benefit with a more veg oriented feeding schedule and in the 3d week I would start them on bloom nutrients.
Are you measuring the feeding strength?You are using quite a few products, be careful you don't over feed your plants.
