She's growing nicely. Still under blurple for now but she has roots coming out the bottom of the pot so will pot her up and put her in the tent this weekend.
Weekend update: transplanted and in the tent.
@CBDTarmac,Thanks for the answer. I also have to acidify the water. Maybe I'll try your way. I also read that lactic acid suppresses the activity of unhealthy microorganisms.
@Mnogumba, Hi thanks for the comment. I use the lactic acid to reduce pH and alkalinity of the water here which is very hard. It works very well and is a lot cheaper than Ph Up/Down solutions. I always have some around as I homebrew a lot of beer too.
