So last night I had adjusted my buckets back down to 5.9 which took huge amounts of ph down (8mls or so on one bucket) but when I checked them an hour later the ph was already back up to 6.2 so I dumped everything for the second time that day and put fresh stuff in. The leaves were also beginning to curl downward but I'm not sure if that was due to the ph changes or just the constant water changes. ANYWAY....this morning they were all at about 6.5 BUT adjusted much more easily with much less ph down and for the most part are uncurled. I will check ph again a few times and change if necessary....no bad smell noticed this morning. .....
