ok so i was away for 2 days adjusted ph as normal on day i left came home today and ph was 5 i adjusted to 5.5 and will bring up to 5.8 tomarrow my question is did i do any damage to my sweet sweet girls they arent looking any different but would be devastated if they turned on me .im in week 7 of flower and never had ph issues till i started useing kool bloom .has anyone else experianced ph drop with kool bloom.

That's not going to cause any problem. If it started with kool bloom, I think I'd stop using it though.
