roots excelurator+rep

does anyone have experience house and garden roots excelurator ? i heard a lot of good things abut it so i bought a 250ml bottle but dont understand the instructions :/
it says "Use Roots Excelurator in the first five weeks of growth mixed with the the other nutes" something like that..
i usually don't feed my plants in the first 3 weeks of growth so does that mean i only use roots excel in weeks 4-5 ?? or can i start using this stuff from week 1 ?
if from week 1 is it every watering or every-other watering ?

thanks in advance for those who'll help

This is strong stuff, but I believe you can and want to use it from day one until a couple weeks into flower at the rate of 1 ml per gallon. Never feed them nutes every watering. Use it every other time or less. Every other time has always worked great for me. Hope that helps.

someone else ??

You want to start using it as soon as you have roots. You can use it from then until beginning of flower.

You can use it every watering, or every other. I don't have much experience with it, I've found other products that work as well for cheaper
