Topping question

Growlog link: [paste your link here]
Hello my name is z. I have a 7 week old plant it’s been in vegg for 4 weeks I just topped my plant today and watered it. Do I keep it on a 18 6 light schedule and do I need to be using nutrition yet and If so what kind and how much. Lastly how long should I keep in vegg till I switch to flowering
*this is a inside grow with one grow light bar blue red white and one heat lamp on room for temperature

Welcome to the community. Firstly you will want to wait about a week or so after tipping to switch just to slow the plant to recover. As far as nutes go what type of growing medium are you using?

Hi @muzzy1128 , welcome to the community.
I agree with @SoulOurGarden , I would wait at least a week, so the plants adjust to the new status.
