Appreciate the assist. Stopped by the local Hydro store this afternoon and picked up a bottle of of the EJ Microblast. The girl there suggested I might try foliar feeding the one plant, and boosting the Magical in my nute mix. The pH question was due to what I read about Mag locking out at 5.7 and below (in the long post on every malady); everything else I've read seems to say 5.5-6.0 is the optimal range for hydro, so I'm going to stick at 5.8 since the other they seem to be thriving (other than the one having a few sick leaves.) Other than those four fan leaves, she (I'm an optimist) is looking great for 27 days from dry seed.
