ok...

ppm is up to 175 (mostly maxigrow, and *titch* of liquid karma (40ml to 25 gallons, very miniscule amount)) they have been consuming about 30+ ppm from the reservoir every night

pH currently 5.6, it had drifted to 6.1

added 10 drops of superthrive to 25 gallons

tied the tops down to make an even canopy

I'm thinking that I should fim them on the very top, try to get the bottom shoots to catch up.
