Scrog attempt #1!

Day 4 and i am finally starting to see them settle in their environment, new growth is now daily visible to the eye. Only thing they are getting now is h2o ph'ed at 6 twice a day. Once as a light mist before lights on and once in the pot. This schedule will continue until i start incorporating some Bio Roots from GHE as from day 10. I am also running an experiment with volcanic rocks. Lady 1 has them in the pot mix, and lady 2 does not. I have seen a lot of positives on these volcanic rocks to help aerate the medium as well as being a source of sulphur and potassium, helping in flower. Anyone has experience with this? The only thing im not happy yet with the setup is the humidity and temperature inside. Trying to figure out this week how to drop both, thinking of adding a more powerful fan for the extraction at the moment and maybe open the tent for a few hours during lights on. Other than that, going quite smooth...just too slow for my liking lol, wish i could be tying dem branches on the net already!
