so after the last few days i have been watching sweet leaf from group 2 burn where it is closest to the light, thought it was because of the purple max but now i'm not sure. problem wasn't going away on its own so i decided to flush with water at about 5.5 and ph test the run off. i swear it must have been at least 8.0!!!!!!!!! i think its due to the last feed, i was having a hard time ph testing the water because the bat guano made it so gray it was hard to get a feel for what the ph was with the 2 nutes, it seemed alkaline so i added some ph down but obviously not enough. i hope this solves some problems. i have had fan leaves from the bottom curling up and dying at the bottom of the plant (there is not enough light because the canopy takes most of it, im willing to bet this was significantly adding to the problem i flushed its healthy neighbor and found that the ph was not as high but still around 7! considering the water i was flushing with is at around 5-5.5 ph before im willing to bet the ph on these plants is through the roof!!!! im glad caught this now and before real chaos developed.
