Yes....that's right....for fish. Don't use ph ADJUSTERS for aquariums though.....only the ph testers. (fish adjusters havee too much salt)

The ph of your water AND soil runoff should be between 6.2-6.8. If the ph of your runoff is abnormal I would not use anything but plain, ph correct tap water until you feel the problem is resolved.

PS..in a pinch you can use distilled white vinegar to lower ph and baking soda to raise it.
Weedhound Reviewed by Weedhound on . Nutes or bugs? I have a female sativa who is now in her 8th week of flowering under a 600w hps lamp. about 3 weeks ago, a bunch of little white flying things (white flies?) started to gather more and more frequently and dispose little white balls on fan leaf undersides. they also began leaving yelloy spots about the leaf eating chlorophyll. now, the fanleaves in the bottom half have all fallen off or are on the verge of it, and the problems climbing still. (branch leaves seem virtually unaffected, its Rating: 5
