you can go back but theres no point 20/4 wont make it flower

As long as it's still in veg, you can. Best to let them get some dark time though, IMO. No you do not ever NEED nutrients, it's a matter of choice. There are nutes for vegging and nutes for flowering, it's all up to your discretion what and when to use them. Plant looks good though, how old? Personally I'd let it get a bit bigger before going to 12/12, but that's just me.

4weeks but i dnt want it that tall i wanted about 4 to 3 feet tall

thxs for the advice
