just a tip: don't overlove your plants ... you got enough stuff there to open a chemistry lab ... relax, let the plants grow naturally ... 'more' is usually not 'better' ... it sounds like you've done your homework, and have the basics down, but resist the urge to 'improve' your plants ... imitate nature ... P.S., don't use reverse-osmosis water without replenishing 10ml of Cal-Mag+ per gallon ... happy gardening :smokin:
