FBT5 in Mr. B's has been no trouble at all so far, still moist in there so i've not watered on day 5, spraying the soil with amino, did one foliar this week on day 5. Probably will fix the fan over the weekend so it's pointing straight up. FBT5 is an interesting one, vigorous in many ways, it seems to be working hard below grownd . anyway I'll try to get an in soil pH reading on the Mr. B's asap. but it will mostly be secondary nutrients and co2 from now on.
