For growing in soil: feed at least once per week (but no more than three times per week). For hydroponics or deep water culture systems: reduce the recommended feeds by 25%, and keep water temperature between 68F-72F. Refrain from using airstones because they may cause root rot - use a circulator pump instead. Avoid exposing the reservoir to light to prevent algae build up. Be sure to change the water and adjust the feeds each week. For best results growing in coco coir or other inert media blends: if watering less than once per day, feed every watering (or at minimum, every other watering). If watering one or more times per day, reduce feed concentrations accordingly - do not feed at full strength multiple times per day. Also, supplement additional Cal-Mag and adjust pH to 6.2 in the vegetative stage, and to 6.4 in the bloom stage. Unsure how to adjust the feeds or have any other questions?
