Future #1 is Now

Plant has been getting straight pH balanced water this last week and minimal nutes. It is showing some slight nute burn so I let off a bit and raised the light canopy about 6”. I discovered that what I thought was a calcium or potassium deficiency was actually a rookie grower error by me. I have an RO system that I use to water all my strains in the grow room including this one, but when adding nutes to the water, it takes too long so I had been filling them up with well water. When I had originally tested the well water, I must had used a faulty testing agent as after testing it this last week, I was showing a pH of 7.5 vs. my RO of 6.2. Thus, every time I was adding nutes (multiple times a week) I was significantly fluctuating the pH between regular feedings and nutrient additions. To make matters worse, when I originally thought it was nute burn, I flushed each plant with well water and likely caused additional stress. Anyway, I have since learned that the well water needs to be treated, I only utilize RO water the last few days and plan to do so over this next week. Also, I have turned off the CO2 system as I was starting to see signs of heat stress on a couple of the strains (not this one). The literature I have reviewed suggested that these strains might be able to handle heat closer to 90F but it was also causing issues with high humidity so when I added a dehumidifier, it pushed the day temp to between 90-92F and the overnight temps were not getting low enough (maybe 85F or so). Maybe I could leave out the dehumidifier, but I was getting rH of 70% and didn’t want to risk any bud rot or mildew growth. So for now, I have turned off the CO2 and am getting high temps of 81F with 60% humidity and overnight temps of 74F and 50% humidity. The Future #1 has shown the least signs of stress and is fattening up its buds very nicely. Over the next few weeks I will start monitoring the trichomes for a nice milky color for harvesting.
