Another week goes by, and another piece of old equipment dies... Time for a new PH pen, picked up the BlueLabs pen, a bit expensive but pays to have proper PH - dUh! Buds are stacking, seem a little loose but time will tell. Instead of turning off the light, some pics are in B&W for the next while. Leaf burn/rust/spots still appearing & progressing, might be a PH issue (still not sure what to run at for this ROOTFARM media, probably soil #'s at 6.5). Watering at 6.2, runoff about 6.8 - likely time for a flush too!
