My first time with a hydroponic system - using two individual Oxy Pots to grow Expert Haze, side by side, one a week older than the other. One pot is Hy-Pro A+B hydro feed, the other Ionic Hydro Grow (and Bloom, later).
Initially struggled to get a decent root system. Once they got going, though, there was no stopping them. Roots now filling the pots, 5 weeks from germination.
Main problem is deep mottled browning of the large leaves, and some mild edge curling. Several lost already.
