Love the camo pattern on the pot, lol
I've heard that the nutes those soils come preloaded with will give out in 4-6 weeks, making it necessary for the grower to take over the feeding at that point.
@lilhoe You've been getting good if somewhat disjointed advice. Before doing a hydro run, I'd suggest you have a solid grow in soil under your belt first. That's going to give you better intuition about timing, amounts to water and fertilize, etc.
In hydro, everything happens faster, including screwing up, lol
