So it would seem like this little mafucka has turned a corner thanks to you guys. Growth has picked back up and it has already packed on a new node that looks healthy. I've checked the water a few times and it doesn't seem like it is eating (EC/TDS is stagnant, pH is rising slowly but still within range at ~6.2) but I am not too concerned about that yet since it is growing and looks good.
I also swapped my humidifier from a cool mist to warm mist which raised the tent temp to 80f and the water temp to ~71f. If it gets much higher, I may switch back to the cool mist but my other plants are enjoying the heat and higher RH so I may just cross my fingers that the bennies do their job.
I did notice a few relatively small root strands floating about in the water the last time I checked. I pulled them out and will keep a close eye. I also noticed some discoloration on my water level site tube. I am assuming it is because I didn't trim it or tuck it under the lip and the top was open to the light so I just switched buckets to one without a site tube to remove any possibility of a light leak.
I was REALLY hoping I'd be able to be relatively lazy with this like I am with my organic grows but apparently I can't or at least shouldn't. Oh well, such is life.
