First Time Grow Questions

Hey everybody,

This is my first grow and I'd appreciate any advice I can get.

I notice alot of the leaves on my plants have three leaves on a branch instead of five. Is this a problem?

How do you re-use a plant after harvest? Doesn't everything need to be cleaned or do you start again with clones? What's the process?

I've just been using the standard nutes that came with the stealth hydro kit so far in vegetative stage. I've been thinking of switching to another fertilizer to enhance growth and size. Any recommendations?

The leaves Will Increase in number from 3 to 5 to 7 to 9 to 11 In some cases as the plant ages

I don't understand the question .. I try to clean my tank every week As for weather or no to keep the plants going with clones that's up to you... I'd take the clones as soon as I
knew it was a female put them in a separate cloner with 24 hr. light till they have roots for about a month..... then toss em into the 12/12 lighting....and change your air stones every harvest or 3 months of use at least...?
