Big Bud in Mezzgrow's Lazy River

3/5 -- I think the reservoir is a little warmer than ideal, resulting the heat stress type symptoms. BB#3 seems unphased but the rest look a tad warm. Dropped the PPM too 555, as it was creeping up to 600 a little too comfortably. Been there for three days now with no up or down movement in anything but water level :) Planning to full empty/refill around week 7 or so, hopefully before the trellis. If not, my system should be easy enough to manage trellised. Only need one water swap before flower.
