<span class="link_user">@SMOKHADA</span>, They are different, Top veg is for veg, and Big One is a bloom stimulator, like Delta 9. Big one you have to apply just before the bloom start once, and two more the first weeks of bloom. The stimulator for Veg period is Green Explosion, but you can't replace the Top Veg, they are different.
<span class="link_user">@SMOKHADA</span>, Hi! This has over an year, so I cant, remember exactly. But with autos I try to not overwater them, so maybe 3 waterings per week. And I always try to mantain a 6,5 ph in the soil. And feeding them once a week only. Hope this help you.
