Autopot for Blue Amnesia XXL in coir

Struggling with keeping the climate in the tent right with high RH being a problem. The dehumidifier is great, but heats the room too much. Have moved the tent to a larger room and will see how the girls respond. Last week of feeding, even though 1st Lady looks like she could run longer. The only downside of my autopot system is that both plants run off the same reservoir. The tank was topped up with pH'd water with what was left in there, the resulting mix is just under 150ppm. Next refill will be plain water pH'd to ~6.5. First brown pistils are appearing and fan leaves are changing colour, so the timing seems about right. note on the different pheno's - 1st Lady has quite yellow pistils and a cheesy smell with rounded buds all the way down the stem while 2nd Lady is more true to type, fruity berry smells and gaining a blueish tint with conical upper buds. Due to local laws they were purchased anonymously from a seed bank (Attitude, FTW) and there is every chance i got two different auto's altogether (they came stealth post in a hand labelled baggy)
