Nutes when what n how please

hye guys got some bushy bosai plants goin 4'' pots about 6 weeks in veg not very many nutes used jus wat came with my areo garden what should i use n how then how often because even when i gave them nutes iwould wait a couple days then nute them again jus randomly putting it in the water these are some nice plants for a first grow ill get pics up there doin better than fine jus dont wont anything to happen this far in thanks

with my aeroponic system i add nutes that i already bought(liquid) ... with aerogarden it comes with tabs id wait till plants are 2~3 weeks old... if you have tabs cut it in half first few times and let dissolve in water before putting in aeroponics.... also dont always give it nutes... clean water once a week ... i just wrote this on my iphone so you better understand
