First DWC White Widow Auto

We're moving into flower. Did a round of defoliation at the beginning and end of the week. I loosened training wires as they were cutting into stems, and one i cut off at the root. The plant didn't seem to care. The only real mistake I've made so far has been hesitating to train. Seems to bite me weekly now but it'll never happen again. pH dips about .2/day. I noticed that my light wasn't cutting it for the spread and density of the canopy, so the old BloomsPlus light is now a backup or possibly going to ebay. The new light from mars hydro is incredible, and the plants immediately reacted to even lighting coverage. Doubled the wattage so I can run it dimmer/cooler with the power supply on the roof. they were out of water by the end of the week and were due for a full res change, so rather than do it early I let their levels climb and kept an eye on them. They ended around 850 so I adjusted their fresh tank to 800, added silica, and made an extra few gallons.
