I use Botanicare products as well but I use the prob-bloom and Hydroplex....i'm not too familiar the "plant power" line. dustko is correct imo...you need Cal-Mag if you use RO water. Cal Mag puts back all the good things your RO system takes out of your water (calcium, minerals, etc) so you can not only spend money to take everything out of your water but also spend money to put things back in.

Cal Mag is a biggie. :thumbsup:
Weedhound Reviewed by Weedhound on . Plant trouble, Need help. I have a Ebb& flow system with 3 plants in it, My plants have been on 12/12 light for about 3.5 weeks. Plant tray is flooded every 4 hours for 4 minutes, just enough time to fill the plant tray for 1 minute, while totally full. I am useing 4.25 OZ of Botanicare Power flower, 7.0 tsp of KoolBloom, and 56 ml of Hygrozyme for 7 gallons of RO water at about 5.5-6.0 PH. Only one plant is looking bad. This trouble is only in the middle part of the plant mainly. Little up top but not much. Any Rating: 5
