I'm sorry you guys but I am stuck on those bloom nutes. When I mixed up the grow nutes the ph naturally went to 5.7...never had to adjust it before I put new stuff in. With the pro-bloom when I mix the ph stands at 4.6 until I adjust it up with baking soda before I add it to the rez. I am willing to swear to this in court, lol I have found this grow that the ph will drop a little the first day then start to go up slowly. I also could not keep my ph down with well water which is why I switched to RO.
Weedhound Reviewed by Weedhound on . Drop in pH..but good growth...???? Hi all. I'm about 3 weeks into vegging and my girls look great. Lush and healthy. I've been experiencing slight drops in pH like from 6.0 to 5.7 or 5.7 to 5.5 during the light cycle. I'm not sure what it means or if it's fine or what. TDS at the last rez change (5 days ago) was about 1700 with all nutes and supplements combined. The plants took very well to it. TDS today is 1370 so the plants are using up the nutes. Usually when plants use nutes the pH tends to increase a bit, not Rating: 5
