Using just water no units ??

Hi through out my veg stage iv hardly used any units due to illness and other hassles .. They look just as good as my last crop which I used dutchmasters gold at this stage don't look no different to my last grow ?? I'm now gonna switch to the flowering stage .. Shoud I use my flowering agents now? The nightmare with my illness is it can happen when it wants so then I have to get some one to water them ... And mixing nuits is easy for us . But when u not got a clue it's easier just to use plain old h20.. I feel in a right old pickle .. Any help or advise plz plz give

what are units?

What I would do is mix a strong up soil like fox farms ocean forest and then add some fertilizer to the soil. Use espoma products. What you want to do is make a bomb ass soil so that you only need to water and make minor adjustments over the course of the grow. Make you grow suit your lifestyle for best results.

whole plants life cycle with no liquid nutes

a good, rich soil, will only need a cpl of flower feeds. don't believe the hype. ppl feed way too much. it doesn't want large doses of ferts, it wants a steady supply.
oh yes......imo
