Sweet ZZ - RQS - DWC

1/25 Drain and fill 2-gallon water change in the afternoon: ppm 966, pH 6.1. I have been actively pruning leaves and some suspicious development under the canopy, also continuing to defoliate the top canopy Probably need to defoliate the top a lot more to help with humidity.c 1/26 Some tip bleaching on a few of the central buds - shut off the additional heater and am working to reduce humidity. The filter sleeve is likely getting clogged with hard minerals from tap water in the humidifier and slowing down the turnover of air, which is allowing humidity to increase. I added some humidifier tabs to try and keep the mineral deposits down, but may not be effective enough. Peeled back a little bit of the sleeve and will see how things go over the next few days. 1/28 The plant with the slight signs of nutrient problems has slightly delayed flower development. One of the drawbacks of 4 plants sharing the same 5-gallon reservoir is that it is difficult to cater to picky phenotypes. Buds are looking nice and full though, smell is coming in stronger by the day. Replaced CO2 yeast generator yesterday morning.
