Thanks for the input Noob I will look into this, how do they look otherwise? The ph runoff from the last watering/feeding was 6.3. When I first noticed the leaves, I did a flush and then a feed of an 1/8 of the recommended dose for the grow, have not noticed much more leaves turning brown.
Next feed/watering the NL will get half dosage grow, and BB will do another at 1/8 dosage, to see what happens. If anyone has any suggestions with the BB or should I try another 1/4 with lower ph.
