Autopots and quantum boards - Blue Dream

A lot of lessons learned this week. Since my tap water is very hard and megacrop supposedly upped their cal/mag in the base nutrient, I haven't been adding any calmag. This had been fine for most of the grow so far but they hit a point where they were deficient. The big plant especially started showing lots of signs starting last week. Addressed it by adding 0.3 EC of calmag. My nutrients must not have dissolved all the way because the EC kept drifting up quite a bit so I had to keep adding fresh water to lower it. In preparation for flipping I decided to defoliate below the ScrOG, and I realize now that I should have done this WAY sooner. They were so bushy, and there was a ton of dead and/or yellow growth underneath. I also saw some bits of fuzzy mold on the top of the coco, almost certainly due to my high humidity and the bushy plants keeping all the moisture in. Removed anything that didn't look good. Next grow I'm going to do this much sooner, especially if the plant is bushy. I was going to flip to flower this weekend, but because of the calmag issues I decided to give a couple more days to recover. The new growth seems to be healthy on all the plants, and over the past 24 hours there was a decent growth spurt so I feel like the plant is reacting to having the nutrients it needs again. Tonight I added 0.1 EC of PK booster to the reservoir and turned off the lights. Going to give them 24 hours of darkness before flipping to a 12/12 schedule. I'm a little worried about the temperatures since my basement gets chilly, so I'll be having the lights on during nights.
