Need suggestions on what nutrients i should use

i just began growing some new plants and i was wondering what everyones choices were for nutrients, and how far into vegging should i begin to use them. I already plan on using mir grow to boost the nitrogen but i wasn't sure on which one to get the highest % for nitrogen in the mir grow that i could find was 30% but if anyone knows of one that has an even higher percentage please let me know. today marks two weeks exactly into vegging so if someone could give me their thoughts that would be appreciated thank you

How do the plants look they will tell you when they need nutes and if they havnt it is probably fine, if you must feed start off at 1/4 strength and work with your plants needs and not on a schedule and you both will be happier for it

i use formulex nutrient solution and hesi nutes and all my plants stay healthy with no nitrogen defficiency until the final week or 2 which is normal...peace

they look fine right now but my buddy just lost 2 of his plants that were 2 months old and it was because of no nutes and they died within 2 or 3 days so i'd rather not wait until they show me that they need it and i already know to start at 1/4 strength and work my way up but thanks anyways bro i still need suggestions on what nutes to use so if u have any let me know
