When adjusting PH, always add small amounts at a time. Allow some time for reactivity. If you do add too much of one you CAN add the other to bring it back. It does NOT affect things. But, that being said, what is the PH before adjustment? Hydro or Soil or Soilless? 5.5-6.5 is a good range to deal with. It's NOT an exact science. Never has been. Never will. Think of it this way......"How does Mother Nature deal with PH issues?" She is self correcting. Plants also will to one extent or the other adjust the PH value to their preference. Over feeding causes a low PH value in your Media. Under feeding(mostly never happens) creates a higher value. PPM shouldn't exceed the wattage being used. General rule of thumb. There are some exceptions to this rule---genetics-age/size of your plant.
Salt based ferts. are made for immediate uptake. Designed to push. Organics are more of a time release. To be taken over time. When she's ready.
Personally, We do NOT use PH adjusters. EVER. It's un-necessary. And over rated. Some will scoff at this comment. BUT, let me assure you that with 30+ years experience this is where we ended up. Once you understand how to mix, how to apply the food and how the plants react to it. It becomes pure candy. Also-------read up on beneficial microbes and fungi. These are the true secret to organic gardening. Microbelife, Oregonismxl, Mykos, Buffaloam, Morm castings, Humus, etc.........
Your environment directly affects how your babies will feed and drink. Control, control, control. Always apply less. Allow time for her to react to it. Less is more.
Keep in mind----not all genetics like the same food. Some prefer organics over all else. Some prefer salt based products over organics. Always start small. Let the garden tell you what's up.
2 number one issues that most people go thru----Too much light. Too much food.
good luck....
