Rising Ph
Wicked_Stixanswered grow question 5 years ago
It seems that ph is the biggest issue people struggle with in hydro. It is usually one of 2 issues. Either nutrients that don't run stable or bacteria breeding causing an unbalanced environment in your reservoir. To rule out the bacteria issue add 2 tsp per gallon of 3% hydrogen peroxide to your reservoir. This will kill any bacteria and add oxygen to the water at the same time. I always run it in my system week 1 just to be safe. As for the nutrients I use maxigro and maxibloom. They buffer pH great and will run stable all week. It is also really cheap. Those 2 things will solve your pH issues and make life a lot easier. Good luck

Did you soak or wash off your hydroton before using? If not that will cause your PH to rise quite a bit.. not to mention all the dust that will be in your reservoir.

In my DWC experience, veg always rises pH and flower lowers it. If your reservoir smells funky I would redo (and clean ) it and add some beneficial bacteria like hydro guard and increase the oxygen and try to stop any light from leaking

Hard water vs CalMagI don't have EC/PPM meters, but I know that I have hard tap water, according to my city water distribution company. Do I need to suplement CalMag on my feedings? How much should I use if I don't have PPM meters here? What are the risks of using or not using CalMag in this case?Week 1

Biobizz Light-Mix vs All-MixCan Biobizz Light Mix sustain the entire life of an autoflowering (plus nutrients, obviously) or should be used for seedlings and first week? All Mix would a be better choice, or in the end just save you some nutrients and work? And for a classic photoperiodic? Your thoughts :)Feeding. Other

Very old Ata BloombasticI own a very old (around 8 years) bottle of Ata Bloombastic. It should not expire, but it looks dark brown and dense (seriously, it looks like liquid s**t but still smells good) but on commercials it appears to be more green than brown. Should I risk it or change it?Feeding. Other
