Hydro pH levels increasing- why?

Hi there.
So I have been using distilled water and checking to make sure the pH level is close to 6.
Yesterday both tanks in my Aerogarden Farm were measuring 5.85 but today they are both up to 6.5. This is the second time this happened.
Does anyone know why there is an increase in alkalinity so quickly? I didn't add anything to it. Is it absorption of nutrients ?
Thanks!
 
It is the plants doing what they will with the nutrients. It sounds like they were pretty hungry. The girls taking up nitrogen will pull the pH up fast. Depending on what nutrients you're using, there may be other biological processes happening. I end up using a lot of pH Down in veg then lots of pH up in flower.
 
At four and a half weeks into veg, they are obviously hongry. You can add a fraction of a normal feed before the next water change. Just make sure you're checking ppm as well as pH. If ppm is high enough already, just adjust pH and don't feed.

ppm is running 380... but leaves are starting to turn yellow after 5 days of feeding... at week 5 now...

No idea. I just saved that image from another thread in here. But i guess you can find it by googling phrases or save the picture and do a reverse picture search to find the original thread in 420 magazine
