Peters uses alot of urea/ammonia nitrogen and little nitrate nitrogen.(not good) It also contains .05% copper and zinc which is alot (too much). It lacks calcium and has little magnesium. The flora series may contain the cal/mag and may have a better ratio of the micros. It also may contain alot of nitrate nitrogen vs. ammonia/urea.(which is good) Check the label.peafunk said:Hello every body
