What soil are you using? I use ocean forest by
foxfarm and its packed with enough nutrients to get me through veg without nuting no problem. I still nute though. You may consider a half dose of nutes if your using a good soil like this because it will be easier to burn your plants. After 2 weeks id say its safe to use full strenght.
I use
general organics full line of nutrients. At the grow store I noticed the
roots organics and was curious so I asked the guy at the store. He told me that roots organic and
general organics are pretty equivalent so I didnt switch. But since were both using similar nutrients I hope this helped ya out a little bit. Most measurents are about 5ml per gallon. I think the most common measuents are 1ml 5ml and 10 ml per gallon. All though I once used
technaflora non-organic and that stuff was 15ml per gallon.
I hope this helped ya some. Happy growing. :)
