Figured id add a little to whats happening now.
Currently i am feeding strictly rain water and Tiger Bloom, waters pH is at 6.0 still with feeding water as well as the run off.
As far as how the medium is holding up, it is good. Yesterday the photo period plant i had in veg showed signs of male preflowers, it was removed and disposed of. One thing i would like to mention about him was, that he was in a one gallon planter had nine tops and all tops were above 13in. After pulling him out of the planter i was pleased to see that this 2 month old plant was not root bound at all. No circular patters of roots, middle, top, or bottom. The entire medium was consumed buy roots. This shows proper aeration through out the root system. I have always been a firm believer of a healthy root system. If you give them what they need and give them proper aeration they will reward you with healthy foliage and dense buds. I think taking care of the root system is one of the most important roles other than adequate light that are key to a successful grow and yield.
The jems medium is of the same mix, after she is done i will post a pic of her root ball.
