I have noticed PH tends to start to drop as the rez hits about day 7 or 8 and the plant has spit some waste back into it. Im not sure if i'm right though on my reasoning. Anyone?
BlazeIdo Reviewed by BlazeIdo 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
