Good eye bro; I certainly was ignoring it somewhat. Clearly that back wall on that tent is cooler in that room; which overhangs to the North Wall of the building. Need to put a thermostat back there I guess.Why are they all looking so sad...
So yea; it's certainly been very cool at night in the house; especially this last week when I wasn't up at night; it's clearly a calcium issue... and there's no shortage of calcium on my formula (I use calcium hydroxide) + calcium nitrate.... pH is dialed correct.
So it's got to be the cold. My guess is it's got down toward 15 C or around 60F in here at times and running usually in the mid to upper 60's; also it's been dry (40's RH some days) in here some days; so it's probably a combination VDP issue with the low temps and low humidity.... transitioning in and out of transpiration. Clearly calcium; and maybe a bit of N. I did some adjustments; and I'll bring up the heat some.
