m0useanswered grow question 3 years ago The transition happens after the light switch or during deepening how you like to grow.
I normally wait aorund a week witch over the feed to the bloom booster I use. I grow in dry amendments not liquid nutrients.
I also still feed in some of the grow feed as nitrogen is still needed.
Most feeds have schedules for you to follow and they are almost fool proof.
I don't see what brand your feeding your plants.
Check out their manufactures web page and find a schedule it should guide you the rest of the way.
